Safety information

EMU33622

Outboard motor safety

Observe these precautions at all times.

EMU36501

Propeller

People can be injured or killed if they come in

contact with the propeller. The propeller can

keep moving even when the motor is in neu-

tral, and sharp edges of the propeller can cut

even when stationary.

● Stop the engine when a person is in the wa-

ter near you.

● Keep people out of reach of the propeller,

even when the engine is off.

EMU33630

Rotating parts

Hands, feet, hair, jewelry, clothing, PFD

straps, etc. can become entangled with inter-

nal rotating parts of the engine, resulting in se-

rious injury or death.

Keep the top cowling in place whenever pos-

sible. Do not remove or replace the cowling

with the engine running.

Only operate the engine with the cowling re-

moved according to the specific instructions in

the manual. Keep hands, feet, hair, jewelry,

clothing, PFD straps, etc. away from any ex-

posed moving parts.

EMU33640

Hot parts

During and after operation, engine parts are

hot enough to cause burns. Avoid touching

any parts under the top cowling until the en-

gine has cooled.

EMU33650

Electric shock

Do not touch any electrical parts while starting

or operating the engine. They can cause

shock or electrocution.

EMU33671

Engine shut-off cord (lanyard)

Attach the engine shut-off cord so that the en-

gine stops if the operator falls overboard or

leaves the helm. This prevents the boat from

running away under power and leaving peo-

ple stranded, or running over people or ob-

jects.

Always attach the engine shut-off cord to a

secure place on your clothing or your arm or

leg while operating. Do not remove it to leave

the helm while the boat is moving. Do not at-

tach the cord to clothing that could tear loose,

or route the cord where it could become en-

tangled, preventing it from functioning.

Do not route the cord where it is likely to be

accidentally pulled out. If the cord is pulled

during operation, the engine will shut off and

you will lose most steering control. The boat

could slow rapidly, throwing people and ob-

jects forward.

EMU33810

Gasoline

Gasoline and its vapors are highly flam-

mable and explosive. Always, refuel accord-

ing to the procedure on page 26 to reduce the

risk of fire and explosion.

EMU33820

Gasoline exposure and spills

Take care not to spill gasoline. If gasoline

spills, wipe it up immediately with dry rags.

Dispose of rags properly.

If any gasoline spills onto your skin, immedi-

ately wash with soap and water. Change

clothing if gasoline spills on it.

If you swallow gasoline, inhale a lot of gaso-

line vapor, or get gasoline in your eyes, get

immediate medical attention. Never siphon

fuel by mouth.

EMU33900

Carbon monoxide

This product emits exhaust gases which con-

tain carbon monoxide, a colorless, 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 ex-

haust outlets.

EMU33780

Modifications

Do not attempt to modify this outboard motor.

Modifications to your outboard motor may re-

duce safety and reliability, and render the out-

board unsafe or illegal to use.

EMU33740

Boating safety

This section includes a few of the many im-

portant safety precautions that you should fol-

low when boating.

EMU33710

Alcohol and drugs

Never operate after drinking alcohol or taking

drugs. Intoxication is one of the most common

factors contributing to boating fatalities.

EMU33720

Personal flotation devices

Have an approved personal flotation device

(PFD) on board for every occupant. Yamaha

recommends that you must wear a PFD

whenever boating. At a minimum, children

and non-swimmers should always wear

PFDs, and everyone should wear PFDs when

there are potentially hazardous boating condi-

tions.

EMU33731

People in the water

Always watch carefully for people in the wa-

ter, such as swimmers, skiers, or divers,

whenever the engine is running. When some-

one is in the water near the boat, shift into

neutral and stop the engine.

Stay away from swimming areas. Swimmers

can be hard to see.

The propeller can keep moving even when

the motor is in neutral. Stop the engine when

a person is in the water near you.

EMU33751

Passengers

Consult your boat manufacturer’s instructions

for details about appropriate passenger loca-

tions in your boat and be sure all passengers

are positioned properly before accelerating

and when operating above an idle speed.

Standing or sitting in non-designated loca-

tions may result in being thrown either over-

board or within the boat due to waves, wakes,

or sudden changes in speed or direction.

Even when people are positioned properly,

alert your passengers if you must make any

unusual maneuver. Always avoid jumping

waves or wakes.

EMU33760

Overloading

Do not overload the boat. Consult the boat ca-

pacity plate or boat manufacturer for maxi-

mum weight and number of passengers. Be

sure that weight is properly distributed ac-

cording to the boat manufacturers instruc-

tions. Overloading or incorrect weight

distribution can compromise the boats han-

dling and lead to an accident, capsizing or

swamping.

EMU33772

Avoid collisions

Scan constantly for people, objects, and other

boats. Be alert for conditions that limit your

visibility or block your vision of others.

Operate defensively at safe speeds and keep

a safe distance away from people, objects,

and other boats.

● Do not follow directly behind other boats or

waterskiers.

ZMU06025

U63V2DE0.book Page 2 Monday, February 22, 2010 9:00 AM

Safety information

3

● Avoid sharp turns or other maneuvers that

make it hard for others to avoid you or un-

derstand where you are going.

● Avoid areas with submerged objects or

shallow water.

● Ride within your limits and avoid aggressive

maneuvers to reduce the risk of loss of con-

trol, ejection, and collision.

● Take early action to avoid collisions. Re-

member, boats do not have brakes, and

stopping the engine or reducing throttle can

reduce the ability to steer. If you are not

sure that you can stop in time before hitting

an obstacle, apply throttle and turn in anoth-

er direction.

EMU33790

Weather

Stay informed about the weather. Check

weather forecasts before boating. Avoid boat-

ing in hazardous weather.

EMU33880

Passenger training

Make sure at least one other passenger is

trained to operate the boat in the event of an

emergency.

EMU33890

Boating safety publications

Be informed about boating safety. Additional

publications and information can be obtained

from many boating organizations.

EMU33600

Laws and regulations

Know the marine laws and regulations where

you will be boating- and obey them. Several

sets of rules prevail according to geographic

location, but all are basically the same as the

International Rules of the Road.

Boat horsepower rating

WARNING

EWM01560

Overpowering a boat can cause severe in-

stability.

Before installing the outboard motor(s), con-

firm that the total horsepower of your out-

board motor(s) does not exceed the boats

maximum horsepower rating. See the boat’s

capacity plate or contact the manufacturer.

EMU33571

Mounting motor

WARNING

EWM01570

● Improper mounting of the outboard mo-

tor could result in hazardous conditions

such as poor handling, loss of control,

or fire hazards.

● Because the motor is very heavy, spe-

cial equipment and training is required

to mount it safely.

Your dealer or other person experienced in

proper rigging should mount the motor using

correct equipment and complete rigging in-

structions. For further information, see page

19.

EMU25694

Battery requirements

EMU25730

Without a rectifier or Rectifier Regula-

tor

NOTICE

ECM01090

A battery cannot be connected to models

that do not have a rectifier or Rectifier

Regulator.

If you wish to use a battery with the models

without a rectifier or Rectifier Regulator, install

an optional Rectifier Regulator.

Using a maintenance-free battery with the

above models can shorten the life of the bat-

tery significantly.

Install an optional Rectifier Regulator or use

accessories rated to withstand 18 volts or

higher with the above models. Consult your

Yamaha dealer for details on installing an op-

tional Rectifier Regulator.

EMU34194

Propeller selection

Next to selecting an outboard motor, selecting

the right propeller is one of the most important

purchasing decisions a boater can make. The

type, size, and design of your propeller have

a direct impact on acceleration, top speed,

fuel economy, and even engine life. Yamaha

designs and manufactures propellers for ev-

ery Yamaha outboard motor and every appli-

cation.

Your outboard motor came with a Yamaha

propeller selected to perform well over a

range of applications, but there may be uses

where a different propeller would be more ap-

propriate.

Your Yamaha dealer can help you select the

right propeller for your boating needs. Select

a propeller that will allow the engine to reach

the middle or upper half of the operating

range at full throttle with the maximum boat-

U63V2DE0.book Page 9 Monday, February 22, 2010 9:00 AM

Specifications and requirements

10

load. Generally, select a larger pitch propeller

for a smaller operating load and a smaller

pitch propeller for a heavier load. If you carry

loads that vary widely, select the propeller that

lets the engine run in the proper range for your

maximum load but remember that you may

need to reduce your throttle setting to stay

within the recommended engine speed range

when carrying lighter loads.

To check the propeller, see page 45.

EMU25770

Start-in-gear protection

Yamaha outboard motors or Yamaha-ap-

proved remote control units are equipped with

start-in-gear protection device(s). This feature

permits the engine to be started only when it

is in neutral. Always select neutral before

starting the engine.

EMU25651

Engine oil requirements

If the recommended engine oil is not avail-

able, another 2-stroke engine oil with an

NMMA-certified TC-W3 rating may be used.

EMU36360

Fuel requirements

EMU36771

Gasoline

Use a good quality gasoline that meets the

minimum octane rating. If knocking or pinging

occurs, use a different brand of gasoline or

premium unleaded fuel. Yamaha recomends

that you use alcohol-free (see Gasohol) gas-

oline whenever possible.

NOTICE

ECM01981

● Do not use leaded gasoline. Leaded gas-

oline can seriously damage the engine.

● Avoid getting water and contaminants in

the fuel tank. Contaminated fuel can

cause poor performance or engine dam-

age. Use only fresh gasoline that has

been stored in clean containers.

Gasohol

There are two types of gasohol: gasohol con-

taining ethanol (E10) and that containing

methanol. Ethanol can be used if the ethanol

content does not exceed 10% and the fuel

meets the minimum octane ratings. All etha-

nol blends containing more than 10% ethanol

can cause fuel system damage or cause en-

gine starting and running problems. Yamaha

does not recommend gasohol containing

methanol because it can cause fuel system

damage or engine performance problems.

EMU36880

Muddy or acidic water

Yamaha strongly recommends that you have

your dealer install the optional chromium-plat-

ed water pump kit if you use the outboard mo-

tor in muddy or acidic water conditions.

However, depending on the model it might not

be required.

Anti-fouling paint

A clean hull improves boat performance. The

boat bottom should be kept as clean of marine

growth as possible. If necessary, the boat bot-

tom 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.

EMU36341

Motor disposal requirements

Never illegally discard (dump) the motor.

Yamaha recommends consulting the dealer

about discarding the motor.

EMU36352

Emergency equipment

Keep the following items onboard in case

there is trouble with the outboard motor.

● A tool kit with assorted screwdrivers, pliers,

wrenches (including metric sizes), and

electrical tape.

● Waterproof flashlight with extra batteries.

● An extra engine shut-off cord (lanyard) with

clip.

EMU25961

Throttle indicator

The fuel consumption curve on the throttle in-

dicator shows the relative amount of fuel con-

sumed for each throttle position. Choose the

setting that offers the best performance and

fuel economy for the desired operation.

EMU25976

Throttle friction adjuster

A friction device provides adjustable resis-

tance to movement of the throttle grip or the

remote control lever, and can be set accord-

ing to operator preference.

To increase resistance, turn the adjuster

clockwise. To decrease resistance, turn the

adjuster counterclockwise. WARNING! Do

not overtighten the friction adjuster. If

there is too much resistance, it could be

difficult to move the remote control lever

or throttle grip, which could result in an

accident.

[EWM00032]

When constant speed is desired, tighten the

adjuster to maintain the desired throttle set-

ting.

EMU25994

Engine shut-off cord (lanyard) and

clip

The clip must be attached to the engine shut-

off switch for the engine to run. The cord

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

cord will pull out the clip, stopping ignition to

the engine. This will prevent the boat from

running away under power. WARNING! At-

tach the engine shut-off cord to a secure

place on your clothing, or your arm or leg

while operating. Do not attach the cord to

clothing that could tear loose. Do not route

the cord where it could become entangled,

preventing it from functioning. Avoid acci-

dentally pulling the cord 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 ob-

jects in the boat to be thrown forward.
