OPERATION

CRUISING

Engine Speed
For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p.
help you hold a steady speed.
For rough water conditions or large
waves, slow down to prevent the
propeller from rising out of the water.
The engine is equipped with an
overrev limiter to prevent the
possibility of mechanical damage
from excessive engine speed.
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.
48
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.
45 ) to
Trim
Install the outboard motor at the best
trim angle for stable cruising and
maximum power.
Trim angle too large: Incorrect
causes boat to ''squat''.
Trim angle too small: Incorrect
causes boat to ''plow''.
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.
Under normal conditions, the boat
will perform best when the
antiventilation plate is level with the
water.
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.
