WARNING
Improper trim tab adjustment can cause dif-

The trim tab is also an anti-corrosion anode.
Disintegration of the anode can effect boat
handling  and  performance.  Make  sure  the
trim  tab  is  in  good   condition  and  adjust
properly.

propeller shaft is not running parallel to the water’s
surface. The trim tab is  adjustable to compensate
for this steering torque.

IMPORTANT: A single trim tab adjustment will re-
lieve steering effort under only one set of speed,
motor angle and load conditions. No single adjust-
ment  can  relieve  steering  effort  under  all  speed,
motor angle and load conditions. If the boat pulls to
the left or right when its load is evenly distributed,
adjust the trim tab as follows:
With  the  motor  shut  OFF,  loosen  the  trim  tab
screw. If the boat pulled to the right, move the rear
of the trim tab slightly to the right. If the boat pulled
to the left, move the rear of the trim tab slightly to
the left.
