OPERATION
Excessive trim/tilt angle during
operation can cause propeller
ventilation, overheating, and water
pump damage.
If, for example, the outboard motor
is tilted excessively, or propeller
ventilation occurs during a sharp turn,
the engine may overrev, activating
the overrev limiter.
The engine is equipped with an
overrev limiter to prevent the
possibility of mechanical damage
from excessive engine speed.
For rough water conditions or large
waves, slow down to prevent the
propeller from rising out of the water.
If engine speed becomes unstable at
high speed due to activation of the
overrev limiter, reduce speed and
check the trim angle of the outboard
motor.
Use the power trim/tilt switch to trim
the outboard motor for the best
performance and stability.
You can use the power trim/tilt
switch at any time, whether the boat
is under way or stopped.
Press the UP or DN (down) side of
the switch to adjust the angle of the
outboard motor.
It is necessary to trim the angle of the
outboard motor to compensate for
changes in boat load, weight
distribution, water conditions, or
propeller selection.
For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p.
to help you hold a steady speed.
Refer to the trim meter (p.
) for an
indication of whether the motor is
trimmed high or low.
Under normal conditions, the boat
will perform best when the
antiventilation plate is level with the
water surface.
When cruising into a high wind, trim
the outboard motor down slightly to
level the boat and improve stability.
With a tail wind, trim the outboard
motor up slightly.
