An excessive trim/tilt angle during
operation can cause propeller
ventilation, overheating, and water
pump damage. This type of damage
is not covered by the

TRIM TAB ADJUSTMENT
137
If steering effort is not equal in both
directions, adjust the trim tab to
compensate for ‘‘torque steer,’’
which is the reaction of the outboard
motor to propeller rotation.

Refer to
on p.
.
When the trim tab is correctly
adjusted, steering effort will be equal
in both directions.
When operating in shallow water, use
the power trim/tilt switch (p.
) to
tilt the outboard motor so that the
propeller and gear case won’t hit the
bottom.
Proceed at low speed, and monitor
water flow from the cooling system
indicator (p.
) to be sure the
outboard motor is not tilted so high
that the water intakes are out of the
water.
Adjust the trim tab with the engine
stopped. Remove the gear case
grommet. Loosen the bolt above the
trim tab, turn the trim tab, and then
tighten the bolt and install the gear
case grommet securely.
