Trim Tab; Shallow Water Operation - Honda BF40D Owner's Manual

TRIM TAB

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.
TRIM TAB BOLT
PROPELLER
Adjust the trim tab with the engine
stopped. Loosen the trim tab bolt
above the trim tab, turn the trim tab,
and then tighten the bolt securely.
When the trim tab is correctly
adjusted, steering effort will be equal
in both directions.
Refer to TRIM TAB ADJUSTMENT
on p. 72.
SHALLOW WATER
OPERATION
LHT, LRT and XRT Types
When operating in shallow water, use
the power trim/tilt switch (p. 61) to
tilt the outboard motor so that the
propeller and gear case won't hit the
TRIM TAB
bottom.
Proceed at low speed, and monitor
water flow from the cooling system
indicator (p. 34) to be sure the
outboard motor is not tilted so high
that the water intakes are out of the
water.
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 Distributor's
Limited Warranty (p. 124).
OPERATION
LH Type
When operating in shallow water, tilt
the outboard motor, using the tilt
lever, so the propeller and gear case
won't hit the bottom.
