If the outboard motor is installed too
low, the boat will squat and be hard
to plane, and the motor will spray
water that may enter the boat. It will
tend to porpoise, and high-speed
stability will be reduced.

If the outboard motor is installed too
high, that will cause propeller
ventilation.

Optimum installation height varies
with boat type and bottom shape.
Contact the boat manufacturer for
any special recommendations that are
unique to a specific model of boat.

If the transom needs to be modified
to accommodate the outboard motor,
contact the boat manufacturer and
follow their recommendations for
corrective action.

Adverse effect to the engine can
occur if the installation position of
the outboard motor is too low. Trim/
tilt down the outboard motor with the
boat fully loaded and stop the engine.
Check that the idle port is 5.9 in (150
mm) or more above the water level.

Use the transom angle adjustment rod
(p.

) to adjust the angle of the

outboard motor so the propeller is
perpendicular to the surface of the
water.

Attach a rope from the boat to the
hole in the stern bracket. This will
help to prevent accidental loss of the
outboard motor.

Attach the stern bracket to the boat
transom by tightening the clamp
screws.
