Safety information
●Before mounting or operating the outboard
motor, read this entire manual. Reading it
should give you an understanding of the
motor and its operation.
●Before operating the boat, read any own-
er’s or operator’s manuals supplied with it
and all labels. Be sure you understand each
item before operating.
●Do not overpower the boat with this out-
board 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 horsepower capacity of the boat.
If the rated horsepower capacity of the boat
is unknown, consult the dealer or boat man-
ufacturer.
●Do not modify the outboard. Modifications
could make the motor unfit or unsafe to use.
●Incorrect propeller selection and incorrect
use may not only cause engine damage,
but also adversely affect fuel consumption.
Consult your dealer for correct use.
●Never operate after drinking alcohol or tak-
ing drugs. About 50% of all boating fatalities
involve intoxication.
●Have an approved personal flotation device
(PFD) on board for every occupant. It is a
good idea to wear a PFD whenever boat-
ing. At a minimum, children and non-swim-
mers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating condi-
tions.
●Gasoline is highly flammable, and its va-
pors are flammable and explosive. Handle
and store gasoline carefully. Make sure
there are no gas fumes or leaking fuel be-
fore starting the engine.
●This product emits exhaust gases which
contain carbon monoxide, a colorless,
odorless gas which may cause brain dam-
age or death when inhaled. Symptoms in-
clude nausea, dizziness, and drowsiness.
Keep cockpit and cabin areas well ventilat-
ed. Avoid blocking exhaust outlets.
●Check throttle, shift, and steering for proper
operation before starting the engine.
●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.
●Know the marine laws and regulations
where you will be boating - and obey them.
●Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
●Tell someone where you are going: leave a
Float Plan with a responsible person. Be
sure to cancel the Float Plan when you re-
turn.
●Use common sense and good judgment
when boating. Know your abilities, and be
sure you understand how your boat han-
dles 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.

●Always watch carefully for swimmers during
the engine operation.
●Stay away from swimming areas.
●When a swimmer is in the water near you
shift into neutral and shut off the engine.
●Do not illegally discard empty containers
used to replace or replenish oil. For the cor-
rect processing of empty containers, con-
sult the dealer where you purchased the oil.
●When replacing oils used to lubricate the
product (engine or gear oil), be sure to wipe
away any spilt oil. Never pour oil without us-
ing a funnel or similar device. If necessary,
verify the necessary replacement proce-
dure with the dealer.
●Never illegally discard (dump) the product.
Yamaha recommends consulting the deal-
er on discarding the product.

Fueling instructions
WARNING
EWM00010
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!
●Do not smoke when refueling, and keep
away from sparks, flames, or other
sources of ignition.
●Stop engine before refueling.
●Refuel in a well-ventilated area. Refuel
portable fuel tanks off the boat.
●Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags.
●Do not overfill the fuel tank.
●Tighten the filler cap securely after refu-
eling.
●If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.
●If any gasoline spills onto your skin, im-
mediately wash with soap and water.
Change clothing if gasoline spills on it.
●Touch the fuel nozzle to the filler open-
ing or funnel to help prevent electrostat-
ic sparks.
CAUTION:
ECM00010
Use only new clean gasoline which has
been stored in clean containers and is not
contaminated with water or foreign matter.
