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 brief-

ly 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.

EMU25500

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 agen-

cies. You should be aware of these rules,

and follow them whenever you encounter

another vessel on the water.

“The general prudential rule”

This rule is called Rule 2 in the International

Rules and says,

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 pro-

vided for your convenience only. Consult

your local U.S. Coast Guard Auxiliary or De-

partment of Motor Vehicles for a complete

set of rules governing the waters in which

“In obeying and construing these rules due

regard shall be had to all dangers of naviga-

tion and collision, and to any special circum-

stances, which may render a departure from

the above rules necessary in order to avoid

immediate danger.”

In other words, follow the standard rules ex-

cept when a collision will occur unless both

vessels try to avoid each other. If that is the

case, both vessels become “Give-Way” ves-

you will be using your boat.

EMU25520

Steering and sailing rules and sound

signals

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 ves-

sel head-on)

Crossing: (you are traveling across the oth-

er vessel’s path)

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” vessel.

These rules determine which vessel has the

right-of-way, and what each vessel should

do.

Overtaking: (you are passing or being

passed by another vessel)

Other special situations

There are three other rules you should be

aware of when driving your boat around oth-

er 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

Fishing vessel right-of-way

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, restrict-

ed areas, danger areas, and general infor-

mation.

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

Remember, markings may vary by geo-

graphic location. Always consult local boat-

ing authorities before driving your boat in

unfamiliar waters.

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-driv-

en 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 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 navigat-

ing in a particular direction. The markings on

these buoys are oriented from the perspec-

tive of being entered from seaward (the boat-

er is going towards the port). This means that

red buoys are passed on the starboard

(right) side when proceeding from open wa-

ter into port, and black buoys are to port (left)

side. When navigating out of port, your posi-

tion with respect to the buoys should be re-

versed; red buoys should be to port and

black buoys to starboard.

EMU25742

Propeller selection

The performance of your outboard motor will

be critically affected by your choice of propel-

ler, 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. Propeller diameter in inches

2. Propeller pitch in inches

3. Type of propeller (propeller mark)

Yamaha outboard motors are fitted with pro-

pellers 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 suit-

able as it enables the correct engine speed

to be maintained. Conversely, a larger-pitch

propeller is more suitable for a smaller oper-

ating load.

NOTE:

Select a propeller which will allow the engine

to reach the middle or upper half of the oper-

ating range at full throttle with the maximum

boat load. If operating conditions such as

light boat loads then allow the engine r/min to

rise above the maximum recommended

range, reduce the throttle setting to maintain

WARNING

CAUTION:

Improper mounting of the outboard mo-

such as poor handling, loss of control, or

fire hazards. Observe the following:

G For permanently mounted models, your

dealer or other person experienced in

proper rigging should mount the motor.

If you are mounting the motor yourself,

you should be trained by an experi-

enced person.

Incorrect engine height or obstructions

to smooth water flow (such as the design

or condition of the boat, or accessories

such as transom ladders or 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.

G For portable models, your dealer or oth-

er person experienced in proper out-

board motor mounting should show

you how to mount your motor.

NOTE:

During water testing check the buoyancy of

the boat, at rest, with its maximum load.

Check that the static water level on the ex-

haust housing is low enough to prevent wa-

ter entry into the powerhead, when water

rises due to waves when the outboard is not

running.

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.

Ring Free Fuel Additive

Gasoline is a precise blend of many different

substances, each chosen to give certain

characteristics. Gasoline blends have been

changing in recent years in response to con-

cerns about pollution and resulting emis-

sions regulations. One of the most obvious

changes has been the elimination of lead

from most fuels.

As gasoline has changed, the amount of ad-

ditives such as aromatics and oxygenates

has increased. These additives are impor-

tant for the engines in passenger cars, but

they can have detrimental effects in marine

engines, because of increased deposits in

the combustion chamber. When enough de-

posits collect, piston rings begin sticking.

Performance drops and engine wear in-

creases dramatically.

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

tank cap, loosen it 2 or 3 turns.

While many additives available may reduce

deposits, Yamaha recommends the use of

Ring Free Fuel Additive, available from

your Yamaha dealer. Ring Free Fuel Addi-

tive has repeatedly proven its ability to clean

combustion deposits from inside the engine,

notably the critical piston-ring-land area, and

Trimming outboard motor

The trim angle of the outboard motor helps

determine the position of the bow of the boat

in the water. Correct trim angle will help im-

prove performance and fuel economy while

reducing strain on the engine. Correct trim

angle depends upon the combination of

boat, engine, and propeller. Correct trim is

also affected by variables such as the load in

G Use caution when trying a trim position

for the first time. Increase speed gradu-

ally and watch for any signs of instabil-

ity or control problems. Improper trim

angle can cause loss of control.

^GUse the power tilt switch located on the

bottom engine cowling (if equipped)

only when the boat is at a complete

stop with the engine off.

WARNING

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 in-

creases 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.

NOTE:

To adjust the trim angle while the boat is

moving, use the power trim and tilt switch lo-

cated on the remote control device or tiller

handle, if equipped.

EMU27911

Adjusting boat trim

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

results in less drag, greater stability and effi-

ciency. This is generally when the keel line of

the boat is up about 3 to 5 degrees. With the

bow up, the boat may have a greater tenden-

cy to steer to one side or the other. Compen-

sate for this as you steer. The trim tab can

also be adjusted to help offset this effect.

When the bow of the boat is down, it is easier

to accelerate from a standing start onto

plane.

Bow Down

Too much trim-in causes the boat to “plow”

through the water, decreasing fuel economy

and making it hard to increase speed. Oper-

ating 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 opera-

tion difficult and dangerous.

NOTE:

Depending on the type of boat, the outboard

motor trim angle may have little effect on the

trim of the boat when operating.

Bow Up

Too much trim-out puts the bow of the boat

too high in the water. Performance and econ-

omy are decreased because the hull of the

boat is pushing the water and there is more

air drag. Excessive trim-out can also cause

the propeller to ventilate, which reduces per-

formance further, and the boat may “por-

poise” (hop in the water), which could throw

the operator and passengers overboard.

EMU27933

Tilting up and down

If the engine will be stopped for some time or

if the boat is moored in shallows, the out-

attempt to diagnose any problems yourself.

Instead, take the outboard motor to a

Yamaha dealer. You should periodically re-

move 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 re-

place the spark plug with another of the cor-

rect type.

Cleaning and adjusting spark plug

EWM00560

WARNING

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 com-

ponent and is easy to inspect. The condition

of the spark plug can indicate something

about the condition of the engine. For exam-

ple, if the center electrode porcelain is very

white, this could indicate an intake air leak or

carburetion problem in that cylinder. Do not

WARNING

Leaking fuel can result in fire or explo-

sion.

^GCheck for fuel leakage regularly.

^GIf any fuel leakage is found, the fuel

system must be repaired by a qualified

mechanic. Improper repairs can make

the outboard unsafe to operate.

Check the fuel lines for leaks, crack, or mal-

function. If a problem is found, your Yamaha

dealer or other qualified mechanic should re-

pair it immediately.

2. Spark plug I.D. mark (NGK)

Spark plug gap:

0.8–0.9 mm (0.031–0.035 in)

When fitting the plug, always clean the gas-

ket 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:

18.0 Nm (13.3 ft-lb) (1.84 kgf-m)

NOTE:

If a torque-wrench is not available when you

are fitting a spark plug, a good estimate of

the correct torque is 1/4 to 1/2 a turn past fin-

ger-tight. Have the spark plug adjusted to the

correct torque as soon as possible with a

torque-wrench.

^GAn unguarded, rotating flywheel is very

dangerous. Keep loose clothing and
