Safety information
EMU33623
Outboard motor safety
Observe these precautions at all times.
EMU36502
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
water near you.
Keep people out of reach of the propeller,
even when the engine is off.
EMU40272
Rotating parts
Hands, feet, hair, jewelry, clothing, personal
flotation device (PFD) straps, etc., can be-
come entangled with internal rotating parts of
the engine, resulting in serious injury or
death.
Keep the top cowling in place whenever pos-
sible. Do not remove or replace the top cowl-
ing with the engine running.
Only operate the engine with the top cowling
removed according to the specific instruc-
tions in the manual. Keep hands, feet, hair,
jewelry, clothing, PFD straps, etc., away from
any exposed moving parts.
EMU33641
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.
EMU33651
Electric shock
Do not touch any electrical parts while start-
ing or operating the engine. They can cause
shock or electrocution.
EMU33661
Power trim and tilt
Body parts can be crushed between the mo-
tor and the clamp bracket when the motor is
trimmed or tilted. Keep body parts out of this
area at all times. Be sure no one is in this area
before operating the power trim and tilt
mechanism.
The power trim and tilt switches operate even
when the main switch is off. Keep people be
away from the switches whenever working
around the motor.
Never get under the lower unit while it is tilted,
even when the tilt support lever is locked. Se-
vere injury could occur if the outboard motor
accidentally falls.
EMU33672
Engine shut-off cord (lanyard)
Attach the engine shut-off cord so that the
engine 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 be-
come entangled, preventing it from function-
ing.
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.
U6DV75E0.book Page 1 Tuesday, February 21, 2017 8:33 AM

EMU33811
Gasoline
Gasoline and its vapors are highly flamma-
ble and explosive. Always, refuel according
to the procedure on page 51 to reduce the
risk of fire and explosion.
EMU33821
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.
EMU33901
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
exhaust outlets.
EMU33781
Modifications
Do not attempt to modify this outboard mo-
tor. Modifications to your outboard motor
may reduce safety and reliability, and render
the outboard unsafe or illegal to use.
EMU33741
Boating safety
This section includes a few of the many im-
portant safety precautions that you should
follow when boating.
EMU33711
Alcohol and drugs
Never operate after drinking alcohol or taking
drugs. Intoxication is one of the most com-
mon factors contributing to boating fatalities.
EMU40281
Personal flotation devices (PFDs)
Have an approved PFD on board for every
occupant. Yamaha recommends that you
must wear a PFD whenever boating. At a mi-
nimum, children and non-swimmers should
always wear PFDs, and everyone should
wear PFDs when there are potentially hazard-
ous boating conditions.
EMU33732
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.
EMU33752
Passengers
Consult your boat manufacturer’s instruc-
tions for details about appropriate passenger
locations in your boat and be sure all passen-
gers are positioned properly before acceler-
ating and when operating above an idle
speed. Standing or sitting in non-designated
locations may result in being thrown either
overboard or within the boat due to waves,
wakes, or sudden changes in speed or direc-
tion. Even when people are positioned prop-
erly, alert your passengers if you must make
any unusual maneuver. Always avoid jump-
ing waves or wakes.
EMU33762
Overloading
Do not overload the boat. Consult the boat
capacity plate or boat manufacturer for maxi-
mum weight and number of passengers. Be
sure that weight is properly distributed ac-
cording to the boat manufacturer’s instruc-
U6DV75E0.book Page 2 Tuesday, February 21, 2017 8:33 AM

Safety information
3
tions. Overloading or incorrect weight
distribution can compromise the boats han-
dling and lead to an accident, capsizing or
swamping.
EMU33773
Avoid collisions
Scan constantly for people, objects, and oth-
er 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.
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 aggres-
sive maneuvers to reduce the risk of loss of
control, 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 an-
other direction.
EMU33791
Weather
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
EMU33881
Passenger training
Make sure at least one other passenger is
trained to operate the boat in the event of an
emergency.
EMU33891
Boating safety publications
Be informed about boating safety. Additional
publications and information can be obtained
from many boating organizations.
EMU33602
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
EWM01561
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.
EMU40491
Mounting outboard motor
WARNING
EWM02501
Improper mounting of the outboard mo-
tor could result in hazardous conditions
such as poor handling, loss of control,
or fire hazards.
Because the outboard motor is very
heavy, special equipment and training is
required to mount it safely.

Your dealer or other person experienced in
proper rigging should mount the outboard
motor using correct equipment and complete
rigging instructions. For further information,
see page 43.
EMU34954
Digital electronic control re-
quirements
The digital electronic control is equipped with
a start-in-gear protection device(s). This de-
vice prevents the engine from starting unless
it is in neutral.
WARNING
EWM01581
If the engine starts in gear, the boat can
move suddenly and unexpectedly, pos-
sibly causing a collision or throwing
passengers overboard.
If the engine ever starts in gear, the
start-in-gear protection device is not
working correctly and you should dis-
continue using the outboard. Contact
your Yamaha dealer.
This digital electronic control unit is only
available for the outboard motor which you
have purchased.
Prior to use of the digital electronic control
unit, set it in order to operate your outboard
motor only. Otherwise, it will not be possible
to operate the outboard motor.
Perform setting of the outboard motor and
the digital electronic control unit in the follow-
ing cases.
If a used outboard motor is installed
If the digital electronic control unit is re-
placed
If the ECM (Electronic control module) of
the used outboard motor is replaced
If the ECM (Electronic control module) of
the digital electronic control unit is re-
placed
Consult your Yamaha dealer for setting.

Battery isolator
Your outboard motor is capable of charging
an accessory battery separate from the start-
ing battery using an optional isolator lead.
Contact your Yamaha dealer for installation
of an optional isolator lead with over-current
protection.
EMU41603
Propeller selection
Next to selecting an outboard motor, select-
ing the right propeller is one of the most im-
portant purchasing decisions a boater can
make. The type, size, and design of your pro-
peller have a direct impact on acceleration,
top speed, fuel economy, and even engine
life. Yamaha designs and manufactures pro-
pellers for every Yamaha outboard motor and
every application.
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 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.
Yamaha recommends to use a propeller suit-
able for the “Shift Dampener System (SDS)”.
For further information, consult your Yamaha
dealer.
To check the propeller, see page 78.
EMU36313
Counter rotation models
Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise and are typically used in multiple motor
setups.
On counter rotation models, be sure to use a
propeller intended for counterclockwise rota-
tion. These propellers are identified with the
letter “L” after the size indication on the pro-
peller. WARNING! Never use a standard
propeller with a counter rotation motor, or
a counter rotation propeller with a stan-
dard motor. Otherwise the boat could go
in the direction opposite of that expected
(for example, reverse instead of forward),
which could lead to an accident. [EWM01811]
For instructions on propeller removal and ins-
tallation, see page 79.
EMU35141
Start-in-gear protection
Yamaha outboard motors or Yamaha-ap-
proved digital electronic control units are
equipped with start-in-gear protection de-
vice(s). This feature permits the engine to be
started only when it is in neutral. Always se-
lect neutral before starting the engine.
