BATTERY REQUIREMENT

cC
Do not use a battery that does not meet
the specified capacity. If a battery which
differs from the specification is used, the
electrical system may perform poorly or
be overloaded, causing electrical system
damage.
Choose a battery which meets the follow-
ing specifications.
Minimum cold crank performance
512 Amps at -17.8°C (0°F)
Minimum reserve capacity
182 Minutes at 26.7°C (80°F)
If any electrical accessories are used, use
a second battery to power them. Choose
a battery with the same capacity as the
one for the engine. If the engine's battery
voltage drops to approximately 9 volts or
below during operation or while starting,
the electric fuel pump for the Electronic
Fuel Injection system will not operate.
The engine can not be started if battery
voltage is too low.

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.
