OPERATION
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 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. Tighten 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. Tighten the bolt
securely. Make small adjustments at a time and
retest. Incorrect trim tab adjustment
can cause adverse steering.
