BATTERY REQUIREMENT

cC
Do not use a battery that does not meet
the specified capacity. If a battery which
does not meet specifications is used, the
electric system could perform poorly or
901015
be overloaded, causing electric system
damage.
For electric start models, choose a battery
which meets the following specifications.
EMU01857
Minimum cold cranking amps (CCA/EN):
430 amps at -18°C (-0.4°F)
Minimum rated capacity (20HR/IEC):
70 A·h

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.
