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 right
turns:
Loosen the trim tab tightening bolt
and turn the rear end of the trim tab
toward the right. Tighten the bolt
securely.
Remove the gear case grommet and
loosen the tightening bolt to adjust
the trim tab. After adjustment,
reinstall the grommet securely.
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.
Make small adjustments at a time and
retest. Incorrect trim tab adjustment
can cause adverse steering.
