Trim Tab Adjustment - Honda Marine BF40A Owner's Manual

6. OPERATION
Trim Tab Adjustment
RIGHT
TIGHTENING B
The trim tab is provided to adjust for
"torque steer" which is a reaction of
the propeller rotation or propeller
torque. If during a high speed turn an
unequal amount of effort is required to
turn the boat right or left, adjust the
trim tab so that an equal amount of
effort is required.
Distribute the load evenly in the boat
and run the boat in a straight course at
full throttle. Slightly turn the steering
wheel or tiller handle for both right
and left turns to determine the amount
of effort required.
If less effort is required to make left
turns:
Loosen the trim tab tightening bolt
and turn the rear end of the trim tab
toward the left. lighten the bolt
securely.
If less effort is required to make right
turns:
Loosen the trim tab tightening bolt
and turn the rear end of the trim tab
toward the right. lighten the bolt
securely.
Make small adjustments at a time and
retest. Incorrect trim tab adjustment
can cause adverse steering.
The trim tab also functions as a sacrifi-
cial anode.
(NOTICE] Painting
or
coating the
anode will lead to rust and corrosion
damage to the outboard motor
