SAFETY

INFORMATION

8 Before mounting or operating the out-

board motor, read this entire manual.

Reading it should give you an under-

standing of the motor and its operation.

8 Before operating the boat, read any

owner’s or operator’s manuals supplied

with it and all labels. Be sure you under-

stand each item before operating.

8 Do not overpower the boat with this

outboard motor. Overpowering the

boat could result in loss of control. The

rated power of the outboard should be

equal to or less than the rated horse-

power capacity of the boat. If the rated

horsepower capacity of the boat is

unknown, consult the dealer or boat

manufacturer.

8 Know the marine laws and regulations

where you will be boating - and obey

them. Refer to “RULES OF THE ROAD”

section for basic boating rules.

8 Stay informed about the weather.

Check weather forecasts before boating.

Avoid boating in hazardous weather.

8 Tell someone where you are going:

leave a Float Plan with a responsible

person. Be sure to cancel the Float Plan

when you return.

8 Use common sense and good judgment

when boating. Know your abilities, and

be sure you understand how your boat

handles under the different boating

conditions you may encounter. Operate

within your limits, and the limits of your

boat. Always operate at safe speeds,

and keep a careful watch for obstacles

and other traffic.

8 Do not modify the outboard. Modifica-

tions could make the motor unfit or

unsafe to use.

8 Never operate after drinking alcohol or

taking drugs. About 50% of all boating

fatalities involve intoxication.

8 Have an approved personal flotation

device (PFD) on board for every occu-

pant. It is a good idea to wear a PFD

whenever boating. At a minimum, chil-

dren and non-swimmers should always

wear PFDs, and everyone should wear

PFDs when there are potentially haz-

ardous boating conditions.

8 Gasoline is highly flammable, and its

vapors are flammable and explosive.

Handle and store gasoline carefully.

Make sure there are no gas fumes or

leaking fuel before starting the engine.

8 Always watch carefully for swimmers

during the engine operation.

8 Stay away from swimming areas.

Stand-on Vessel

The vessel with the right-of-way has the

duty to continue its course and speed,

except to avoid an immediate collision.

When you maintain your direction and

speed, the other vessel will be able to

determine how best to avoid you.

BASIC BOATING RULES

(Rules of the road)

Just as there are rules which apply when

you are driving on streets and high ways,

there are waterway rules which apply when

you are driving your boat. These rules are

used internationally, and are also enforced

by the United States Coast Guard and local

agencies. You should be aware of these

rules, and follow them whenever you

encounter another vessel on the water.

Give-way Vessel

The vessel which does not have the right-

of-way has the duty to take positive and

timely action to stay out of the way of the

Stand-On vessel. Normally, you should not

cross in front of the vessel with the right-of-

way. You should slow down or change

directions briefly and pass behind the other

vessel. You should always move in such a

way that the operator of the other vessel

can see what you are doing.

Several sets of rules prevail according to

geographic location, but are all basically the

same as the International Rules of the

Road. The rules presented here in your

Owner’s Manual are condensed, and have

been provided for your convenience only.

Consult your local U.S. Coast Guard Auxil-

iary or Department of Motor Vehicles for a

complete set of rules governing the waters

in which you will be using your boat.

“The general prudential rule”

This rule is called Rule 2 in the Inter-

national Rules and says,

‘In obeying and construing these rules

due regard shall be had to all dangers of

navigation and collision, and to any spe-

cial circumstances, which may render a

departure from the above rules neces-

sary in order to avoid immediate dan-

ger.’

STEERING AND SAILING RULES

AND SOUND SIGNALS

Whenever two vessels on the water meet

one another, one vessel has the right-of-

way; it is called the “stand-on” vessel. The

vessel which does not have the right-of-way

is called the “give-way” or “burdened” ves-

sel. These rules determine which vessel

has the right-of-way, and what each vessel

should do.

In other words, follow the standard rules

except when a collision will occur unless

both vessels try to avoid each other. If that

is the case, both vessels become “Give-

Way” vessels.

other vessel on your port (left) side. This

rule doesn’t apply if both of you will clear

one another if you continue on your set

course and speed.

RULES WHEN ENCOUNTERING

VESSELS

There are three main situations which you

may encounter with other vessels which

could lead to a collision unless the Steering

Rules are followed:

Meeting

(you are approaching another vessel

head-on)

Crossing

(you are travelling across the other ves-

sel’s path)

Overtaking

102044

(you are passing or being passed by

another vessel)

Crossing

When two power driven vessels are cross-

ing each other’s path close enough to run

the risk of collision, the vessel which has

the other on the starboard (right) side must

keep out of the way of the other. If the other

vessel is on your right, you must keep out of

its way; you are the Give-Way vessel. If the

other vessel is on your port (left) side,

remember that you should maintain course

and direction, provided the other vessel

gives you the right-of-way as it should.

In the following illustration, your boat is in

the center. You should give the right-of-way

to any vessels shown in white area (you are

the Give-Way vessel). Any vessels in the

shaded area must yield to you (they are the

Give-Way vessels). Both you and the meet-

ing vessel must alter course to avoid each

other.

102045

102046

Meeting

If you are meeting another power vessel

head on, and are close enough to run the

risk of collision, neither of you has the right-

of-way! Both of you should alter course to

avoid an accident. You should keep the

Overtaking

If you are passing another vessel, you are

the “Give-Way” vessel. This means that the

other vessel is expected to maintain its

course and speed. You must stay out of its

maintain your speed and direction so that 3. In a narrow channel, a sailing vessel

the other vessel can steer itself around you.

OTHER SPECIAL SITUATIONS

There are three other rules you should be

aware of when driving your boat around

other vessels.

should not hamper the safe passage of

a power-driven vessel which can navi-

gate only in such a channel.

Reading Buoys and Other Markers

The waters of the United states are marked

for safe navigation by the lateral system of

buoyage. Simply put, buoys and markers

have an arrangement of shapes, colors,

numbers and lights to show which side of

the buoy a boater should pass on when

navigating in a particular direction. The

markings on these buoys are oriented from

the perspective of being entered from sea-

ward (the boater is going towards the port).

This means that red buoys are passed on

the starboard (right) side when proceeding

from open water into port, and black buoys

are to port (left) side. When navigating out

of port, your position with respect to the

buoys should be reversed; red buoys

should be to port and black buoys to star-

board.

Narrow Channels and Bends

When navigating in narrow channels, you

should keep to the right when it is safe and

practical to do so. If the operator of a

power-driven vessel is preparing to go

around a bend that may obstruct the view of

other water vessels, the operator should

sound a prolonged blast on the whistle (4 to

6 seconds). If another vessel is around the

bend, it too should sound the whistle. Even

if no reply is heard, however, the vessel

should still proceed around the bend with

caution. If you navigate such waters with

your boat, you will need to carry a portable

air horn, available from local marine supply

stores.

Fishing Vessel Right-of-way

Many bodies of water used by boaters are

entirely within the boundaries of a particular

state. The Uniform State Waterway Marking

System has been devised for these waters.

This system uses buoys and signs with dis-

tinctive shapes and colors to show regulato-

ry or advisory information. These markers

are white with black letters and orange

boarders. They signify speed zones,

restricted areas, danger areas, and general

information.

All vessels which are fishing with nets, lines

or trawls are considered to be“fishing ves-

sels” under the International Rules. Vessels

with trolling lines are not considered fishing

vessels. Fishing vessels have the right-of-

way regardless of position. Fishing vessels

cannot, however, impede the passage of

other vessels in narrow channels.

Sailing Vessel Right-of-way

Sailing vessels should normally be given

the right-of-way. The exceptions to this are:

1. When the sailing vessel is overtaking

the power-driven vessel, the power-dri-

ven vessel has the right-of-way.

Remember, markings may vary by geo-

graphic location. Always consult local boat-

ing authorities before driving your boat in

unfamiliar waters.

GASOLINE (PETROL)

Recommended gasoline:

Regular unleaded gasoline with a

minimum octane rating of 86 (Pump

Octane Number) = (R+M)/2

If knocking or pinging occurs, use a differ-

ent brand of gasoline or premium unlead-

ed fuel. If unleaded gasoline is not avail-

able, then leaded regular gasoline can be

used.

EMU00027

Gasohol

There are two types of gasohol: gasohol

containing ethanol and that containing

methanol. Gasohol containing ethanol

can be used if ethanol content does not

exceed 10% and the fuel meets minimum

octane ratings. Gasohol containing

methanol is not recommended by Yama-

ha because it can cause fuel system dam-

age or engine performance problems.

EMU00858

ENGINE OIL

Recommended engine oil:

YAMALUBE 2 STROKE OUTBOARD

OIL

If the recommended engine oil is not

available, another 2-stroke engine oil with

a NMMA-certified TC-W3 rating may be

used.

BATTERY REQUIREMENT

Do not use the battery that does not

meet the specified capacity. If different

battery from the specification is used, the

electric system may perform poorly or be

overloaded, causing electrical system

damage.

Choose battery which meets the following

specifications for Electric start model.

EMU01395

PROPELLER SELECTION

The performance of your outboard motor

will be critically affected by your choice of

propeller, as an incorrect choice could

adversely affect performance and could

also seriously damage the motor. Engine

speed depends on the propeller size and

boat load. If engine speed is too high or

too low for good engine performance,

this will have an adverse effect on the

engine.

1-12

Yamaha outboard motors are fitted with

propellers chosen to perform well over a

range of applications, but there may be

uses where a propeller with a different

pitch would be more appropriate. For a

greater operating load, a smaller-pitch

propeller is more suitable as it enables

the correct engine speed to be main-

tained. Conversely, a larger-pitch pro-

peller is more suitable for a smaller oper-

ating load.

14-1/2x17-M

602022

Yamaha dealers stock a range of pro-

pellers, and can advise you and install a

propeller on your outboard that is best

suited to your application.

NOTE:

At full throttle and under a maximum

boat load, the engine’s rpm should be

within the upper half of the full throttle

operating range, as listed in “SPECIFICA-

TIONS” on page 4-1. Select a propeller

which fulfills this requirement.

If operating under conditions which allow

the engine’s rpm to rise above the maxi-

mum recommended range (such as light

boat loads), reduce the throttle setting to

maintain the rpm in the proper operating

range.

Engine stop lanyard switch

The lock-plate on the end of the lanyard

must be attached to the engine stop

switch for the engine to run. The lanyard

should be attached to a secure place on

the operator’s clothing, or arm or leg.

Should the operator fall overboard or

leave the helm, the lanyard will pull out

the lock plate, stopping ignition to the

engine. This will prevent the boat from

running away under power.

8 Attach the engine stop switch lanyard

to a secure place on your clothing, your

arm or leg while operating.

8 Do not attach the lanyard to clothing

that could tear loose. Do not route the

lanyard in such a way that it could

become entangled, preventing it from

functioning.

8 Avoid accidentally pulling the lanyard

during normal operation. Loss of

engine power means the loss of most

steering control. Also, without engine

power, the boat could slow rapidly.

This could cause people and objects in

the boat to be thrown forward.

Fuel consumption also varies slightly

with the type of water (salt, fresh, and

and humidity, cleanliness of the boat

bottom, engine mounting height, skill of

the operator, and individual gasoline

formulation (winter or summer fuel and

amount of additives).

8 The Yamaha digital speedometer and

speed, miles traveled, and fuel econo-

my by water movement at the stern of

the boat. This distance can vary greatly

from the actual distance traveled

because of water currents, sea swells,

and the condition of the water speed

sensor (partially plugged or damaged).

8 Individual engines may slightly vary in

their fuel consumption due to manufac-

turing variations. These variations can

be even greater if the engines are of dif-

ferent year models. In addition, varia-

tions in propellers, even of the same

basic dimensions of the same design,

can also cause a slight variation in fuel

consumption.

INSTALLATION

Incorrect engine height or obstructions

to smooth water flow (such as the

design or condition of the boat or acce-

ssories such as transom ladders/depth

finder transducers) can create airborne

water spray while the boat is cruising.

Severe engine damage may result if the

motor is operated continuously in the

presence of airborne water spray.

NOTE:

During water testing check the buoyancy of

the boat, at rest, with its maximum load.

Check that the static water level on the

exhaust housing is low enough to prevent

water entry into the powerhead, when water

rises due to waves when the outboard is not

running.

Improper mounting of the outboard

motor could result in hazardous condi-

tions such as poor handling, loss of con-

trol, or fire hazards. Observe the follow-

ing:

tion is intended as reference only. It is

Proper

combination.

mounting depends in part on experi-

bination.

8 Your dealer or other person experi-

enced in proper rigging should mount

the motor. If you are mounting the

motor yourself, you should be trained

by an experienced person. [permanent

mounted type]

8 Your dealer or other person experi-

enced in proper outboard motor

mounting should show you how to

mount your motor. [portable type]

Mount the outboard motor on the center

line (keel line) of the boat, and ensure that

the boat itself is well balanced. Otherwise,

the boat will be hard to steer. For boats

without a keel or which are asymmetrical,

consult your dealer.

Overpowering a boat may cause severe

instability. Do not install an outboard

motor with more horsepower than the

maximum rating on the capacity plate of

the boat. If the boat does not have a

capacity plate, consult the boat manufac-

turer.

EMU01299

Mounting Height

To run your boat at optimum efficiency,

the water-resistance (drag) of the boat

and outboard motor must be made as lit-

tle as possible. The mounting-height of

the outboard motor greatly affects the

water-resistance. If the mounting-height

is too high, cavitation tends to occur, thus

reducing the propulsion; and if the pro-

peller tips cut the air, the engine speed

will rise abnormally and cause the engine

to overheat. If the mounting-height is too

low, the water-resistance will increase

and thereby reduce engine efficiency.

Mount the engine so that the anti-cavita-

tion plate is in alignment with the bottom

of the boat .

104014

NOTE:

8 The optimum mounting height of the

outboard motor is affected by the

boat/motor combination. Test runs at

different heights can help determine the

optimum mounting height.

BOARD MOTOR” for instructions on

setting the trim angle of the outboard.

Ring Free Fuel Additive

Gasoline is a precise blend of many differ-

ent substances, each chosen to give certain

characteristics. Gasoline blends have been

changing in recent years in response to

concerns about pollution and resulting

emissions regulations. One of the most

obvious changes has been the elimination

of lead from most fuels.

As gasoline has changed, the amount of

additives such as aromatics and oxy-

genates has increased. These additives are

important for the engines in passenger cars,

but they can have detrimental effects in

marine engines, particularly 2 cycle out-

boards because of increased deposits in

the combustion chamber. When enough

deposits collect, piston rings begin sticking.

Performance drops and engine wear

increases dramatically.

While many additives available may reduce

deposits, Yamaha recommends the use of

Ring Free Fuel Additive, available from

your Yamaha dealer. Ring Free has repeat-

edly proven its ability to clean combustion

deposits from inside the engine, notably the

critical piston-ring-land area, and fuel sys-

tem components. Follow product labeling

FILLING OIL (for Precision blend system

model)

This engine uses the YAMAHA PRECISION

BLEND SYSTEM, which provides superior

lubrication by ensuring the proper oil ratio

for all operating conditions. No fuel premix-

ing is needed (except during break-in/run-

ning-in). Simply pour gasoline into the fuel

tank and oil into the oil tank.

Convenient indicator segments indicate

condition of the oil supply. Refer to oil warn-

ing system.

To fill the engine oil into the oil tanks, pro-

ceed as follows:

Do not add gasoline (Petrol) to the oil

tank. Fire or explosion could result.

905015

Engine oil tank capacity:

Refer to “SPECIFICATION”, page 4-1.

OFF ON START

When remote oil tank is used:

Pour oil into the remote oil tank and turn the

main switch to “ON”, and the YAMAHA

PRECISION BLEND SYSTEM automatical-

ly feeds the oil from the remote oil tank to

the engine oil tank in the top cowling.

701024

After refilling, turn the main switch to “OFF”.

Then, proceed to start the engine. Other-

wise, the oil-level warning system may pre-

vent the engine from revving up.

OFF ON START

When the engine is operated for the first

time or stored for a period of time, a min-

imum of 5 liters (5.3 US qt, 4.4 Imp qt) of

oil should be kept in the remote oil tank.

Otherwise, the oil-feed pump chamber

will not be filled with oil, and no oil will

be supplied.

PRE-OPERATION CHECK

If any item in the pre-operation check is

not working properly, have it inspected

and repaired before operating the out-

board motor. Otherwise, an accident

could occur.

Fuel

Check to be sure you have plenty of fuel

for your trip. Make sure there are no fuel

leaks or gasoline fumes.

Be sure the fuel hose is not being flattened

or kinked by objects in the boat, and that

there are no sharp objects near it.

Oil

Check to be sure you have plenty of oil for

your trip.

Controls

Check throttle, shift, and steering for prop-

er operation before starting the engine.

The controls should work smoothly, with-

out binding or unusual free play. Look for

loose or damaged connections.

Check operation of the starter and stop

switches when the outboard moter is in

the water.

Engine

Check the engine and engine mounting.

Look for loose or damaged fasteners.

Check the propeller for damage.

Do not start the engine out of water.

Overheating and serious engine damage

can occur.

OPERATION AFTER A LONG PERIOD

OF STORAGE

(for precision blend system)

When operating the engine after a long

period (12 months) of storage, proceed as

follows:

1) Use a 50 : 1 gasoline-oil mixture to

start the engine.

2) Start the engine.

Leave it idling.

8 Do not touch or remove electrical parts

when starting or during operation.

8 Keep hands, hair, and clothes away

from flywheel and other rotating parts

while engine is running.

212012

3) Watch for oil flowing through the oil

feed pipes. After any air in the oil

lines has been expelled, YAMAHA

PRECISION BLEND SYSTEM should

supply oil normally. If no oil has

begun flowing after 10 minutes of

idling, consult your Yamaha dealer.

When operating the engine after a long

period of storage, be sure to take the

above steps; otherwise, engine seizure

may occur.

BREAKING IN (RUNNING IN)

ENGINE

Your new engine requires a period of

break-in (running-in) to allow mating sur-

faces of moving parts to wear-in evenly.

Correct break-in (running-in) will help

ensure proper performance and longer

engine life.

8 Failure to follow the break-in (running-

in) procedure may result in reduced

engine life or even severe engine dam-

age.

8 Premix fuel must be used during break-

in (running-in) in addition to oil in the

YAMAHA PRECISION BLEND SYSTEM.

EMU00227

Run the engine under load (in gear with a

propeller installed) as follows.

1) First 10 minutes:

Run the engine at the lowest possi-

ble-speed. A fast idle in neutral is

best.

2) Next 50 minutes:

Do not exceed half throttle (approxi-

mately 3,000 r/min). Vary engine

speed occasionally. If you have an

easy-planing boat, accelerate at full

throttle onto plane, then immediately

reduce the throttle to 3,000 r/min or

less.

3) Second hour:

Accelerate at full throttle onto plane,

then reduce engine speed to three-

quarter throttle (approximately 4,000

r/min). Vary engine speed occasional-

ly. Run at full throttle for one minute,

then allow about 10 minutes of opera-

tion at three-quarter throttle or less to

let the engine cool.

4) Third through tenth hours:

Avoid operating at full throttle for

more than 5 minutes at a time. Let the

engine cool between full-throttle runs.

Vary engine speed occasionally.

5) After the first 10 hours:

Operate the engine normally. Use

straight gasoline (petrol) in the fuel

tank; YAMAHA PRECISION BLEND

SYSTEM provides proper lubrication

for normal operation.

STARTING ENGINE

8 Before starting the engine, make sure

that the boat is tightly moored and that

you can steer clear of any obstructions.

Be sure there are no swimmers in the

water near you.

8 When the air vent screw is loosened,

gasoline (petrol) vapor will be released.

Gasoline (petrol) is highly flammable,

and its vapors are flammable and

explosive. Refrain from smoking, and

keep away from open flames and

sparks while loosening the air vent

screw.

8 This product emits exhaust gases

which contain carbon monoxide, a col-

orless, odorless gas which may cause

brain damage or death when inhaled.

Symptoms include nausea, dizziness,

and drowsiness. Keep cockpit and

cabin areas well ventilated. Avoid

blocking exhaust outlets.

1) If there is an air vent screw on the fuel

tank cap, loosen it 2 or 3 turns.

2) If there is a fuel joint or a fuel cock on

the boat, firmly connect the fuel line

to the joint or open the fuel cock.

3) Squeeze the primer bulb with the out-

let end up until you feel it become

firm.

plate on the other end of the lanyard

in the engine stop switch.

8 Attach the engine stop switch lanyard

to a secure place on your clothing, your

arm or leg while operating.

000293

8 Do not attach the lanyard to clothing

that could tear loose. Do not route the

lanyard where it could become entan-

gled, preventing it from functioning.

8 Avoid accidentally pulling the lanyard

during normal operation. Loss of

engine power means the loss of most

steering control. Also, without engine

power, the boat could slow rapidly.

This could cause people and objects in

the boat to be thrown forward.

WARMING UP ENGINE

1) Before beginning operation, allow the

engine to warm up at idling speed for 3

minutes. (Failure to do this will shorten

engine life.)

2) Check for a steady flow of water from

the cooling-water pilot hole.

309013

A continuous flow of water from the pilot

hole shows that the water pump is

pumping water through the cooling pas-

sages. If water is not flowing out of the

pilot hole at all times while the engine is

running, do not continue to run the

engine. Overheating and serious dam-

age could occur. Stop the engine and

check to see if the water inlet on the

lower casing is blocked. If the problem

cannot be found and corrected, consult

your Yamaha dealer.

TRIMMING OUTBOARD

MOTOR

The trim angle of the outboard motor

helps determine the position of the bow

of the boat in the water. The correct trim

angle will help improve performance and

fuel economy while reducing strain on the

engine. The correct trim angle depends

upon the combination of boat, engine,

and propeller. Correct trim is also affected

by variables such as the load in the boat,

sea conditions, and running speed.

Excessive trim for the operating condi-

tions (either trim up or trim down) can

cause boat instability and can make

steering the boat more difficult. This

increases the possibility of an accident. If

the boat begins to feel unstable or is hard

to steer, slow down and/or readjust the

trim angle.

Refer to the section “ADJUSTING TRIM

ANGLE” for instructions on usage.

EMU01401

Power Trim/Tilt Model

8 Be sure all people are clear of the out-

board motor when adjusting the

trim/tilt angle, also be careful not to

pinch any body parts between the drive

unit and clamp bracket.

702014*

8 Use caution when trying a trim position

for the first time. Increase speed gradu-

ally and watch for any signs of instabili-

ty or control problems.

DOWN

8 Use the power trim/tilt switch located

on the bottom engine cowling (if

equipped) only when the boat is at a

complete stop with the engine off.

The outboard motor trim angle can be

adjusted operating the power trim/tilt

switch 1.

702042*

To raise the bow (“trim-out”), push the

switch UP.

To lower the bow (“trim-in”), push the

switch DN.

Make test runs with the trim set to differ-

ent angles to find the position that works

best for your boat and operating condi-

tions.

NOTE:

To adjust the trim angle while the boat is

moving, use the power trim and tilt

switch located on the remote control

device or tiller handle, if so equipped.

EMU00282

Bow Up

When the boat is on plane, a bow-up atti-

tude result in less drag, greater stability

and efficiency. This is generally when the

keel line of the boat is up about 3 to 5

degrees. When trimmed out, the boat

may have more tendency to steer to one

side or the other. Compensate for this as

you steer. The trim tab can also be adjust-

ed to help offset this effect.

Too much trim-out puts the bow of the

boat too high in the water. Performance

and economy are decreased because the

hull of the boat is pushing the water and

there is more air drag.

Excessive trim-up can cause the propeller

to ventilate, which reduces performance

further. When trimmed-out too much, a

boat may “porpoise” (hop in the water),

which could throw the operator and pas-

sengers overboard.

105011

EMU00283

Bow Down

When the bow of the boat is down, it is

easier to accelerate from a standing start

onto plane.

Too much trim-in causes the boat to

“plow” through the water, decreasing

fuel economy and making in hard to

increase speed.

Operating with excessive trim-in at higher

speeds also makes the boat unstable.

Resistance at the bow is greatly

increased, heightening the danger of

“bow steering” and making operation dif-

ficult and dangerous.

ENGINE RUNNING

Using only one of the engines in case of

emergency, be sure to keep the unused

one tilted up and operate the other engine

at low speed.

102043

If the boat is operated with one engine in

the water but not running, water may run

into the exhaust pipe due to wave action,

causing engine trouble.

NOTE:

When you are maneuvering at low speed,

such as near a dock, it is recommended

that both engines be running with one in

neutral gear. Then, if the engine you are

using stops, you can immediately switch

to the other engine.

EMU01200

TILTING UP/DOWN

If the engine will be stopped for some

time, or if the boat is moored in shallows,

the engine should be tilted up to protect

the propeller and casing from damage by

collision with obstructions, and also to

reduce salt corrosion.

000817

Before tilting the motor, follow the proce-

dures under “STOPPING ENGINE”. Never

tilt the motor while the engine is running.

Severe damage from overheating can

result.

Be sure all people are clear of the out-

board motor when adjusting the tilt

angle, also be careful not to pinch any

body parts between the drive unit and

engine bracket.

Leaking fuel is a fire hazard. Disconnect

the fuel line or close the fuel cock if the

engine will be tilted for more than a few

minutes. Otherwise, fuel may leak. (If the

fuel connector is provided on the motor.)

TRANSPORTING AND

STORING OUTBOARD MOTOR

TRAILERING OUTBOARD MOTOR

The motor should be trailered and stored in

the normal running position. If there is insuf-

ficient road clearance in this position, then

trailer the motor in the tilt position using a

motor support device such as a transom

saver bar.

Do not use the tilt support lever/knob

when trailering the boat. The outboard

motor could shake loose from the tilt

support and fall. If the motor can not be

trailered in the down position, use an

additional support device to secure it in

the up position.

8 Never get under the lower unit while it

is tilted, even if a motor support bar is

used. Severe injury could occur if the

outboard accidentally falls.

8 USE CARE when transporting fuel

tank, whether in a boat or car.

DO NOT fill fuel container to maximum

capacity.

Gasoline will expand considerably as

it warms up and can build up pressure

in the fuel container. This can cause

fuel leakage and a potential fire haz-

ard.

STORING OUTBOARD MOTOR

When storing your Yamaha outboard for

prolonged periods of time, (2 months or

longer), several important procedures must

be performed to prevent expensive dam-

age. This is especially important for your

Precision Blend equipped outboard due to

the lean oil ratios used at idle prior to shut-

ting the engine off for the season.

It is advisable to have your outboard ser-

viced by an authorized Yamaha dealer prior

to storage. However, the following proce-

dures can be performed by you, the owner,

with a minimum of tools.

Filling Fuel Tank

Fill the fuel tank with fresh fuel and add one

ounce of “Yamaha fuel conditioner and sta-

bilizer” (Part No. LUB-FUELC-12-00) to

each gallon of fuel.

NOTE:

The use of Yamaha Fuel Conditioner and

Stabilizer eliminates the need to drain the

fuel system. Consult your Yamaha dealer or

other qualified mechanic if the fuel system

is to be drained instead.

Flushing Cooling System and Fogging

Engine

Cooling system flushing is essential to pre-

vent the cooling system from clogging up

with salt, sand, or dirt. In addition, fogging

of the engine is mandatory to prevent

expensive engine damage due to rust. Per-

form the flushing and fogging at the same

time.

605014

1) Remove the top cowling and silencer

cover. Remove the propeller.

2) Install a flushing attachment to the lower

unit. (Flushing attachment available

from your Yamaha dealer).

Avoid running the outboard at high rpm

while on the flushing attachment or

overheating could occur.

8 Do not touch or remove electrical

parts when starting or during opera-

tion.

8 Keep hands, hair and clothes away

from flywheel and other rotating parts

while engine is running.

3) Run the engine at a fast idle for 10~15

minutes.

4) Just prior to turning off the engine,

quickly spray “Yamaha Stor-Rite Engine

Fogging Oil (Part No. LUB-STRRT-12-

00) alternately into each carburetor.

When properly done, the engine will

smoke excessively and almost stall.

5) Remove the flushing attachment and

wipe off any excess water.

6) Install the silencer cover and top cowl-

ing. Install the propeller.

EMK26110*

Lubrication

1) Remove the spark plugs, and spray a 10

second spray of Yamaha Stor-Rite

Engine Fogging Oil into each cylinder.

Grease the spark plug threads and rein-

stall the spark plugs and torque to prop-

er specification.

(Refer to the Periodic Cleaning and

Inspection section, “Cleanning and

adjusting spark plug.”).

2) Turn the engine over with the stop lan-

yard disconnected to work the fogging

oil into the piston rings.

3) Fill the oil tanks. This prevents the for-

mation of condensation. For models with

a remote tank, it may be necessary to

manually override the control unit to

completely fill the engine main tank.

(Refer to the Troubleshooting section,

“Temporary action in emergency.”).

4) Change the lower unit oil. (Refer to the

Periodic Cleaning and Inpsection sec-

tion, “Changing gear oil.”). Inspect the

oil for the presence of water which indi-

cates a leaky seal. Seal replacement

should be performed by an authorized

Yamaha dealership prior to use.

5) Grease all grease fittings. (Refer to the

Periodic Cleaning and Inspection sec-

tion, “Greasing.”)

EMK27010*

Cleaning and Anti-corrosion Measure

1) Wash down the exterior of the outboard

with fresh water and dry off completely.

2) Spray the engine’s exterior with Yamaha

Silicone Protectant (Part No. LUB-SILC-

NE-13-00).

3) Wax the cowling with a non-abrasive

wax such as Yamaha Silicone Wax

(Part No. ACC-11000-15-02).

CLEANING AND ADJUSTING SPARK

PLUG

When removing or installing a spark plug,

be careful not to damage the insulator. A

damaged insulator could allow external

sparks, which could lead to explosion or

fire.

The spark plug is an important engine

component and is easy to inspect. The

condition of the spark plug can indicate

something about the condition of the

engine. For example, if the center elec-

trode porcelain is very white, this could

indicate an intake air leak or carburetion

problem in that cylinder. Do not attempt

to diagnose any problems yourself.

Instead, take the outboard motor to a

Yamaha dealer. You should periodically

remove and inspect the spark plug

because heat and deposits will cause the

spark plug to slowly break down and

erode. If electrode erosion becomes

excessive, or if carbon and other deposits

are excessive, you should replace the

spark plug with another of the correct

type.

Standard spark plug:

Refer to “SPECIFICATIONS”, page 4-1.

Before fitting the spark plug, measure the

electrode gap with

wire thickness

gauge; adjust the gap to specification if

necessary.

Spark plug gap:

Refer to “SPECIFICATIONS”, page 4-1

_{Download from Www.Somanuals.c}4_om-1_.1_{All Manuals Search And Download.}

When fitting the plug, always clean the

gasket surface and use a new gasket.

Wipe off any dirt from the threads and

screw in the spark plug to the correct

torque.

Spark plug torque:

Refer to “SPECIFICATIONS”, page 4-1.

NOTE:

If a torque-wrench is not available when

you are fitting a spark plug, a good esti-

mate of the correct torque is 1/4 to 1/2 a

turn past finger-tight. Have the spark plug

adjusted to the correct torque as soon as

possible with a torque-wrench.

fluid as it can cause severe burns or

permanent eye injury.

8 Wear protective eye gear when han-

dling or working near batteries.

Antidote (EXTERNAL):

8 SKIN–Flush with water.

8 EYES–Flush with water for 15 minutes

and get immediate medical attention.

Antidote (INTERNAL):

8 Drink large quantities of water or milk

followed by milk of magnesia, beaten

egg, or vegetable oil. Get immediate

medical attention.

Batteries also generate explosive

hydrogen gas; therefore, you should

always follow these preventive mea-

sures:

8 Charge batteries in a well-ventilated

area.

8 Keep batteries away from fire, sparks,

or open flames (e.g., welding equip-

ment, lighted cigarettes, etc.).

8 DO NOT SMOKE when charging or

handling batteries.

8 KEEP BATTERIES AND ELECTROLYT-

IC FLUID OUT OF REACH OF CHIL-

DREN.

A poorly maintained battery will quickly

deteriorate.

1) Check the electrolyte level at least once

a month. Fill to the manufacturer’s rec-

ommended level when necessary.

Top-up only with distilled water (or pure

de-ionized water suitable to use in bat-

teries).

Ordinary tap-water contains minerals

harmful to a battery, and should not be

used for topping-up.

2) Keep the battery always in a good state

of charge. Installing a voltmeter will help

you monitor your battery.

If you will not use the boat for a month

or more, remove the battery from the

boat and store it in a cool, dark place.

Completely recharge the battery before

using it.

3) If the battery will be stored for longer

than a month, check the specific gravity

of the fluid at least once a month and

recharge the battery when it is low.

Connecting the Battery

Mount the battery holder securely in a

dry, well-ventilated, vibration-free loca-

tion in the boat. Install the fully charged

battery in the holder.

8 Make sure the main switch (on applica-

ble models) is “OFF” before working on

the battery.

8 Reversal of the battery leads will dam-

age the rectifier.

8 Connect the RED lead first when

installing the battery and disconnect

the RED lead last when removing it.

Otherwise, the electrical system can be

damaged.

8 The electrical contacts of the battery

and cables must be clean and properly

connected, or the battery will not start

the engine.

Connect the RED lead to the POSITIVE (+)

terminal first. Then connect the BLACK

lead to the NEGATIVE (-) terminal.

8 Using a single battery

Connect both red cables 1 and 2 to the

(+) terminal.

MOTOR EXTERIOR

Cleaning the Outboard Motor

After use, wash the exterior of the out-

board with fresh water. Flush the cooling

system with fresh water.

MU01172

CLEANING COOLING-WATER

PASSAGES

Flushing device equipped model

Perform this procedure right after opera-

tion for the most thorough flushing.

1) After shutting off the engine, unscrew

the garden-hose connector 2 from

the fitting 1 on the bottom cowling.

2) Screw the garden-hose connector 2

onto a garden hose 3 which is con-

nected to a fresh-water supply.

3) With the engine off, turn on the water

tap and let the water flush through

the cooling passages for about 15

minutes. Turn off the water and dis-

connect the garden hose 3.

4) When flushing is complete, reinstall

the garden-hose connector 2 on the

fitting 1 on the bottom cowling.

Tighten the connector securely.

000838

_{Download from Www.Somanuals.c}4_om-2_.9_{All Manuals Search And Download.}

Do not leave the garden-hose connector

loose on the bottom cowling fitting or let

the hose hang free during normal opera-

tion. Water will leak out of the connector

instead of cooling the engine, which can

cause serious overheating. Be sure the

connector is tightened securely on the fit-

ting after flushing the engine.

NOTE:

8 When flushing the engine with the boat

in the water, tilting up the engine until it

is completely out of the water will

achieve better results.

8 Refer to cooling system flushing

instructions in “TRANSPORTING AND

STORING OUTBOARD MOTOR”.

EMU00412

Checking Painted Surface of Motor

Check the motor for scratches, nicks, or

flaking paint. Areas with damaged paint

are more likely to corrode. If necessary,

clean and paint the areas. A touch-up

paint is available from a Yamaha dealer.

EMU00413

COATING THE BOAT BOTTOM

A clean hull improves boat performance.

The boat bottom should be kept as clean

of marine growths as possible. If neces-

sary, the boat bottom can be coated with

an anti-fouling paint approved for your

area to inhibit marine growth.

Do not use anti-fouling paint which

includes copper or graphite. These paints

can cause more rapid engine corrosion.

TEMPORARY ACTION IN

EMERGENCY

EMH80010

IMPACT DAMAGE

The outboard motor can be seriously

damaged by a collision while operating

or trailering. Damage could make the

outboard motor unsafe to operate.

If the outboard motor hits any object in the

water, follow the procedure below;

1) Stop the engine immediately .

2) Inspect control system and all compo-

nents for damage. Also, inspect the boat

damage .

3) However damage is found or not found,

go back to a nearest harbor slowly and

carefully.

607011

4) Have a Yamaha dealer inspection of

the outboard motor, before operating it

again.

EMG65210

POWER TRIM / TILT WILL NOT

OPERATE

If the engine cannot be tilted up or down

with the power trim and tilt because of a

discharged battery or a failure with the

power trim and tilt unit, the engine can be

tilted manually.

STARTER WILL NOT OPERATE

If the starter mechanism does not operate

(engine cannot be cranked with the starter),

the engine can be started with an emer-

gency starter rope.

8 Use this procedure only in an emer-

gency and only to return to port for

repairs.

8 When the emergency starter rope is

used to start the engine, the start-in-

gear protection device does not oper-

ate. Make sure the transmission is in

neutral. Otherwise, the boat could

unexpectedly start to move, which

could result in an accident.

8 Be sure no one is standing behind you

when pulling the starter rope. It could

whip behind you and injure someone.

8 An unguarded rotating flywheel is very

dangerous. Keep loose clothing and

other objects away when starting the

engine. Use the emergency starter

rope only as instructed. Do not touch

the flywheel or other moving parts

when the engine is running. Do not

install the starter mechanism or top

cowling after the engine is running.

8 Do not touch the ignition coil, high

voltage wire, spark plug cap or other

amount of oil can be pumped from the

remote oil tank 3 to the engine oil tank 2

using the emergency switch 1.

218011*

Be sure to stop the engine before per-

forming this procedure.

8 If the emergency switch is held up too

long, too much oil will be pumped into

the engine tank, overflowing it. Release

the switch when oil reaches the upper

level line on the engine oil tank.

218012*

8 Do not use this emergency procedure

unless the oil level warning lamps are

installed and working.

1) Remove the top cowling.

2) Turn the main switch to the “ON”

position.

3) Lift the emergency switch to pump

reserve oil in remote oil tank into the

engine oil tank.

905013*

4) After using the emergency switch,

turn off the main switch, then turn it

back on. This resets the warning sys-

tem for normal operation. Yellow seg-

ment will remain appearing on oil

level indicator at this time.

5) Start the engine and return to the

nearest port for more oil.

TREATMENT OF SUBMERGED

MOTOR

If the outboard motor is submerged, imme-

diately take it a Yamaha dealer. Otherwise,

some corrosion may begin almost immedi-

ately. If you cannot immediately take the

outboard motor to a Yamaha dealer, follow

the procedure below for taking care to mini-

mize engine damage.

107012

1) Thoroughly wash away mud, salt, sea-

weed, etc. with fresh water.

2) Remove the spark plugs, and face the

spark plug holes downward to allow any

water, mud or contaminants to drain.

3) Drain the fuel from the carburetor.

4) Feed fogging oil or engine oil through

the carburetors and spark plug holes

while cranking with the manual starter or

emergency starter rope.

107013

registration card for your records. If you are unsure whether or not your Yamaha is

registered, complete the Warranty Registration card found inside the cover of the

Owner's Manual. Mail it to the distributor for the country in which you live (see step 6 for

the correct address). If your Yamaha is not properly registered, a warranty repair could

be unnecessarily delayed while registration records are checked.

2. Read the Limited Warranty statement which follows these instructions. This warranty

applies to Yamaha outboard motors sold in the United States, whether purchased

separately or when supplied as original equipment by a boat builder. The terms also

apply to original equipment packages sold in Canada, with coverage provided by

Yamaha Motor Canada (see ``Warranty Guide'' for Canadian models). This warranty

explains the conditions of the warranty, including the obligations that your dealer and

you as the owner have under the warranty. For example, your Yamaha outboard must

receive a proper pre-delivery inspection (PDI) by the selling dealer. Failure to take this

important step could jeopardize warranty coverage!

3. If you need warranty repairs, you must take your Yamaha outboard to an authorized

Yamaha outboard dealer. Be aware that not all selling boat dealers are authorized

Yamaha dealers. Only authorized dealers have the factory training, special tools, and

Yamaha support needed to perform warranty repairs.

4. If you are away from home, or your selling dealer is not an authorized Yamaha dealer,

use the following toll-free numbers to find the nearest Yamaha dealer.

United States Dealer Locations: 1-800-692-6242

5. Your warranty applies specifically to repairs made in the country of purchase. If your

U.S.-purchased Yamaha needs warranty service while in Canada, or your Canadian

purchased Yamaha needs service while in the United States, Yamaha will assist the local

dealer whenever possible. However, some products available in one country may not be

sold or serviced in the other.

6. If you need any additional information about your Yamaha or warranty coverage which

your dealer cannot provide, please contact us directly.

WARRANTY QUESTIONS AND ANSWERS

Q. What costs are my responsibility during the warranty period?

A. The customer`s responsibility includes all costs of normal maintenance services, non-warranty repairs, accident and collision

damages.

Q. What are some examples of ``abnormal’’ strain, neglect, or abuse?

A. These terms are general and overlap each other in areas. Specific examples include:

Running the machine out of oil, operating the machine with a broken or damaged part which causes another part to fail, damage or

failure due to improper or careless transportation, and/or tie down. If you have any specific questions on operation or

maintenance, please contact your Yamaha outboard dealer for advice.

Q. Does the warranty cover incidental costs such as towing or transportation due to a failure?

A. No. The warranty is limited to repair of the machine itself.

Q. May I perform any or all of the recommended maintenance shown in the Owner’s Manual instead of having the dealer do them?

A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s and Service Manuals. We do recommend,

however, that items requiring special tools or equipment be done by a Yamaha outboard dealer.

Q. Will the warranty be void or canceled if I do not operate or maintain my new outboard exactly as specified in the Owner’s Manual?

A. No. The warranty on a new outboard cannot be ’’voided`` or ’’canceled``. However, if a particular failure is caused by operation or

maintenance other than as shown in the Owner’s Manual, that failure may not be covered under warranty.

Q. What responsibility does a Yamaha outboard dealer have under this warranty?

A. Each Yamaha outboard dealer is expected to:

1. Completely set up each outboard he sells prior to delivery.

2. Explain the operation, maintenance, and warranty requirements to your satisfaction at the time of sale, and upon your request

at any later date.

In addition, each Yamaha outboard dealer is held responsible for his setup, service and warranty repair work.

Q. Is the warranty transferable to second owners?

A. Yes. The remainder of any existing warranty can be transferred upon request. The unit has to be inspected and re-registered by an

authorized Yamaha outboard dealer for the policy to remain effective.

Welcome to the Yamaha Family!

Congratulations on the purchase of your new Yamaha marine power. Yamaha is

committed to exceptional customer satisfaction, and we want your ownership

experience to be a satisfying one. Please read the following warranty information to

help ensure satisfaction with your Yamaha.

This model was manufactured as a U.S.A. specification model, and the warranty

statement shown in this manual is for market. To receive the benefits of the warranty

that applies to the country in which you use your Yamaha, please note the following

information.

1. The warranty on this model is the same as equivalent models sold in the country

where you will receive service. If you need more information about your warranty

coverage or your Yamaha outside the U.S.A. or Canada, please contact an

authorized Yamaha dealer in your country.

2. Keep a copy of your sales contract or invoice for the purchase of your Yamaha and

present it if you need warranty repairs. This document should show the date of

purchase, which is important evidence the repairing dealer will need to be sure

your Yamaha is covered by warranty.
