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 outboard 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
2
General information
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 de-
●
vice (PFD) on board for every occupant. It
is a good idea to wear a PFD whenever
boating. At a minimum, children and nonswimmers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating conditions.
●
Gasoline is highly flammable, and its vapors 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.
Always watch carefully for swimmers dur-
●
ing 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.

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.

NOTE:
Select a propeller which will allow the engine
to reach the middle or upper half of the operating range at full throttle with the maximum
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.
