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 manufacturer.
● 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-swimmers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating conditions.
● 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 before starting the engine.
● This product emits exhaust gases which
contain 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.
● 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 return.
● Use common sense and good judgment
when boating. Know your abilities, and be
sure you understand how your boat handles 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.

General information
● 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 correct processing of empty containers, consult 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 using a funnel or similar device. If necessary,
verify the necessary replacement procedure with the dealer.
● Never illegally discard (dump) the product.
Yamaha recommends consulting the dealer on discarding the product.

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 gasoline 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 electrostatic sparks.

EMU25742
Propeller selection
The performance of your outboard motor will
be critically affected by your choice of propeller, 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.
Yamaha outboard motors are fitted with propellers 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 suitable as it
enables the correct engine speed to be maintained. Conversely, a larger-pitch propeller is
more suitable for a smaller operating load.
Yamaha dealers stock a range of propellers,
and can advise you and install a propeller on
your outboard that is best suited to your application.

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 the engine in the proper operating range.
For instructions on propeller removal and installation, see page 56.
