Excessive transom angle during
operation can cause propeller
ventilation, overheating, and water
pump damage.For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p. or
p. ) to 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.
Under normal conditions, the boat
will perform best when the
antiventilation plate is level with the
water.
Install the outboard motor at the best
transom angle for stable cruising and
maximum power.
Transom angle too large: Incorrect
causes boat to ‘‘squat’’.
Transom angle too small: Incorrect
causes boat to ‘‘bow steer’’.
It is necessary to adjust the transom
angle of the outboard motor to
compensate for changes in boat load,
weight distribution, water conditions,
or propeller selection.
When cruising into a high wind,
adjust the outboard motor down
slightly to level the boat and improve
stability. With a tail wind, adjust the
outboard motor up slightly (p. ).
