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 25 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
U69M78E0.book Page 2 Monday, April 26, 2010 11:53 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.
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-
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
U69M78E0.book Page 9 Monday, April 26, 2010 11:53 AM

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.

Engine oil requirements
If the recommended engine oil grades are not
available, select an alternative from the fol-
lowing chart according to the average temper-
atures in your area.

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.
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.

EMU36330
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

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.
