8 This product emits exhaust gases which

contain carbon monoxide, a colorless,

odorless gas which may cause brain

damage or death when inhaled. Symp-

toms include nausea, dizziness, and

drowsiness. Keep cockpit and cabin

areas well ventilated. Avoid blocking

exhaust outlets.

8 Check throttle, shift, and steering for

proper operation before starting the

engine.

8 Attach the engine stop switch lanyard

to a secure place on your clothing, or

your arm or leg while operating. If you

accidentally leave the helm, the lanyard

will pull from the switch, stopping the

engine.

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.

SAFETY

Q _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 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

BASIC BOATING RULES

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.

(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 Aux-

iliary 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 Interna-

tional 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 necessary

in order to avoid immediate danger.’

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 “bur-

dened” vessel. 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.

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 Steer-

ing Rules are followed:

Meeting (you are approaching another

vessel head-on)

Crossing (you are traveling across the

other vessel’s path)

Overtaking (you are passing or being

passed by another vessel)

102044

Crossing

When two power driven vessels are

crossing 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 ves-

sel 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 ves-

sels in the shaded area must yield to you

(they are the Give-Way vessels). Both you

and the meeting vessel must alter course

to avoid each other.

102045

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 other vessel on your port (left)

side. This rule doesn’t apply if both of you

102046

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 Sailing vessel right-of-way

of its way until you are clear of it. Like- Sailing vessels should normally be given

wise, if another vessel is passing you, you the right-of-way. The exceptions to this

around you.

the power-driven vessel, the power-

driven vessel has the right-of-way.

2. Sailing vessels should keep clear of

any fishing vessel.

3. In a narrow channel, a sailing vessel

should not hamper the safe passage

of a power-driven vessel which can

navigate only in such a channel.

OTHER SPECIAL SITUATIONS

There are three other rules you should be

aware of when driving your boat around

other vessels.

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 navi-

gate such waters with your boat, you will

need to carry a portable air horn, avail-

able from local marine supply stores.

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 par-

ticular direction. The markings on these

buoys are oriented from the perspective

of being entered from seaward (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 navi-

gating out of port, your position with

respect to the buoys should be reversed;

red buoys should be to port and black

buoys to starboard.

Fishing vessel right-of-way

All vessels which are fishing with nets,

lines or trawls are considered to be “fish-

ing vessels” under the International

Rules. Vessels with trolling lines are not

considered fishing vessels. Fishing ves-

sels have the right-of-way regardless of

position. Fishing vessels cannot, howev-

er, impede the passage of other vessels in

narrow channels.

Many bodies of water used by boaters are

entirely within the boundaries of a partic-

ular state. The Uniform State Waterway

Marking System has been devised for

these waters. This system uses buoys and

signs with distinctive shapes and colors

to show regulatory or advisory informa-

1-9

Download from Www.Somanuals.com. All Manuals Search And Download.

tion. These markers are white with black

letters and orange boarders. They signify

speed zones, restricted areas, danger

areas, and general information.

Remember, markings may vary by geo-

graphic location. Always consult local

boating 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.

If leaded gasoline is usually used, engine

valves and related parts should be

inspected after every 300 hours of opera-

tion.

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.

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.

1-14

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.

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 1 must be attached to the

engine stop lanyard switch for the engine

to run. The lanyard 2 should be attached

to a secure place on the operator’s cloth-

ing, or arm or leg. Should the operator fall

overboard or leave the helm, the lanyard

will pull out the lock plate, stopping igni-

tion to the engine. This will prevent the

boat from running away under power.

000569

8 Attach the 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.

NOTE:

The engine cannot be started with the

lock-plate removed.

angle in relation to the transom. The

power trim/tilt switch is located on the

remote control lever grip. Pushing the

switch “UP” trims the motor up, then tilts

the motor up. Pressing the switch “DN”

tilts the motor down and trims the motor

down. When the switch button is

released, the motor will stop in its current

position.

INSTALLATION

Incorrect engine height or obstructions to

smooth water flow (such as the design or

condition of the boat or accessories such

as transom ladders/depth finder trans-

ducers) can create airborne water spray

while the boat is cruising. Severe engine

damage may result if the motor is operat-

ed continuously in the presence of air-

borne 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 pre-

vent water entry into the powerhead,

when water rises due to waves when the

outboard is not running.

MOUNTING THE OUTBOARD

MOTOR

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:

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 cer-

tain 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 passen-

ger cars, but they can have detrimental

effects in marine engines, because of

increased deposits in the combustion

chamber. When enough deposits collect,

piston rings begin sticking. Performance

drops and engine wear increases dramati-

cally.

While many additives available may

reduce deposits, Yamaha recommends

the use of Ring Free Fuel Additive, avail-

able from your Yamaha dealer. Ring Free

has repeatedly proven its ability to clean

combustion deposits from inside the

engine, notably the critical piston-ring-

land area, and fuel system components.

Follow product labeling for use instruc-

tions.

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.

ANGLE” for instructions on usage.

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.

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

105013

105015

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.

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.

000837

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

Leaking fuel is a fire hazard. When trans-

porting and storing the outboard motor,

close the air vent screw and fuel cock to

prevent fuel from leaking.

EMU00326

TRAILERING OUTBOARD MOTOR

The motor should be trailered and stored

in the normal running position. If there is

insufficient road clearance in this position,

then trailer the motor in the tilt position

using a motor support device such as a

transom saver bar.

For further details, consult your Yamaha

dealer.

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 consid-

erably as it warms up and can build up

pressure in the fuel container. This can

cause fuel leakage and a potential fire

hazard.

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.

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

damage.

It is advisable to have your outboard ser-

viced by an authorized Yamaha dealer

prior to storage. However, the following

procedures can be performed by you, the

owner, with a minimum of tools.

000898

8 To prevent problems which can be

caused by oil entering the cylinder from

the sump, keep the engine in the verti-

cal position when transporting and

storing it.

If storing or transporting the outboard

motor in a horizontal position, put it on

a cushion after draining the engine oil.

8 Do not place the engine on its side

before the cooling water has drained

from it completely, or water may enter

the cylinder through the exhaust port

and cause problems.

8 Store the engine in a dry, well-ventilat-

ed place, not in direct sunlight.

Flushing Cooling System and Fogging

Engine

Cooling system flushing is essential to

prevent the cooling system from clogging

up with salt, sand, or dirt. In addition, fog-

ging of the engine is mandatory to pre-

vent expensive engine damage due to

rust. Perform the flushing and fogging at

the same time.

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.

EMU00342

8 Flushing with the Flushing Attachment

Avoid running the outboard at high

speed while on the flushing attachment,

or overheating could occur.

1) Remove the top cowling and the pro-

peller.

2) Install a flushing attachment 1 to the

cooling water inlet.

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

minutes supplying fresh water.

4) Just prior to turning off the engine,

quickly spray “Yamaha Stor-Rite

Engine Fogging Oil” (Part No. LUB-

STRRT-12-00) alternately into the

silencer cover. When properly done,

the engine will smoke excessively

and almost stall.

Battery Care

Battery electrolyte is poisonous and dan-

gerous, causing severe burns, etc. It con-

tains sulfuric acid. Avoid contact with

skin, eyes, or clothing.

Antidote:

EXTERNAL; Flush with water.

INTERNAL; Drink large quantities of

water or milk. Follow with milk of mag-

nesia, beaten egg, or vegetable oil. Call

physician immediately.

EYES; Flush with water for 15 minutes

and get prompt medical attention.

Batteries produce explosive gases: Keep

sparks, flame, cigarettes, etc. away. Ven-

tilate when charging or using in a closed

space. Always wear eye protection when

working near batteries.

KEEP OUT OF REACH OF CHILDREN.

Batteries vary among manufacturers.

Therefore the following procedures may

not always apply. Consult your battery

manufacturer’s instructions.

1) Disconnect and remove the battery

from the boat. Always disconnect the

black negative lead first to prevent the

risk of shorting.

2) Clean the battery casing and termi-

nals. Fill each cell to the upper level

with distilled water.

3) Store the battery on a level surface in

a cool, dry, well-ventilated place out

of direct sunlight.

4) Once a month, check the specific

gravity of the electrolyte and recharge

as required to prolong battery life.

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.

4-11

Download from Www.Somanuals.com. 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.

ADJUSTING IDLING SPEED

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.

This procedure must be performed while

the outboard motor is in the water. A

flushing attachment or test tank can be

used.

A diagnostic tachometer should be used

for this procedure.

1) Start the engine and allow it to warm

up fully in Neutral until it is running

smoothly. If the outboard is mounted

on a boat, be sure the boat is tightly

moored.

2) Adjust the throttle stop-screw 1 to

set the idling speed to specification

(see “SPECIFICATIONS” on page 4-1)

by turning the stop-screw clockwise

to increase the idling speed, and turn-

ing it counterclockwise to decrease

the idling speed.

F1045

NOTE:

Correct idling-speed adjustment is only

CHECKING BATTERY (for Electric

start model)

Battery electrolytic fluid is dangerous; it

contains sulfuric acid and therefore is poi-

sonous and highly caustic.

Always follow these preventive mea-

sures:

8 Avoid bodily contact with electrolytic

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 han-

dling batteries.

8 KEEP BATTERIES AND ELECTROLYTIC

FLUID OUT OF REACH OF CHILDREN.

4-27

Download from Www.Somanuals.com. All Manuals Search And Download.

8 A poorly maintained battery will quick-

ly deteriorate.

8 Ordinary tap-water contains minerals

harmful to a battery, and should not be

used for topping-up.

1) Check the electrolyte level at least

once a month. Fill to the manufactur-

er’s recommended level when neces-

sary. Top up only with distilled water

(or pure de-ionized water suitable to

use in batteries).

901015

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 grav-

ity of the fluid at least once a month

and recharge the battery when it is

low.

dry, well-ventilated, vibration-free loca-

tion in the boat. Install a 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.

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

emergency 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 gear shift lever/

remote control lever is in neutral. Oth-

erwise, 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 fly-

wheel 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

board motor to a Yamaha dealer, follow

the procedure bellow for taking care to

minimize engine damage.

EMU00448

1) Thoroughly wash away mud, salt,

seaweed, etc. with fresh water.

2) Remove the spark plug(s), then face

the spark plug holes downward to

allow any water, mud or contami-

nants to drain.

3) Drain the fuel from the carburetor,

fuel filter and fuel line. Drain the

engine oil completely.

4) Fill the sump with the fresh engine oil

as the same quantity as the engine oil

capacity.

Engine oil capacity:

Refer to SPECIFICATIONS, Page 4-1.

5) Feed engine fogging oil or engine oil

through the carburetor(s) and spark

plug hole(s) while cranking the

engine with the manual starter or

emergency starter rope.

IMPORTANT WARRANTY INFORMATION FOR U.S.A. AND

CANADA

Welcome to the Yamaha Family!

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

ted to exceptional customer satisfaction, and we want your ownership experience to be

a satisfying one. Please read the following warranty information to help ensure satisfac-

tion with your Yamaha.

Yamaha is ready to stand behind your purchase with strong warranty coverage. To be sure

you receive all the benefits of warranty, please take the following steps:

1. Be sure your new Yamaha is registered for warranty. Your boat dealer should do this at

the time of sale. Make sure your dealer gives you a copy of the completed Yamaha regis-

tration 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 unneces-

sarily 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 sepa-

rately 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 condi-

tions 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 Yama-

ha 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

Canada Dealer Locations:

1-800-267-8577

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 pur-

chased 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 dam-

ages.

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 mainte-

nance, 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.

IMPORTANT WARRANTY INFORMATION

IF YOU USE YOUR YAMAHA OUTSIDE U.S.A. OR CANADA

Welcome to the Yamaha Family!

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

mitted 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 state-

ment 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 infor-

mation.

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 autho-

rized 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.

3. If your Yamaha needs warranty repairs, contact an authorized Yamaha dealer in

the country where you are. He will explain how to get warranty service in that

country.

4. This Yamaha model may not be sold in some countries. Therefore, in some cases

your local dealer may not have all the parts or service information he may need,

which may unavoidably delay repairs. If this happens, we thank you for your

understanding and assure you we will attempt to resolve the situation as quickly as

possible.
