Install the propeller nut and torque to:
•
156 in. lbs. (18 N·m)
If cotter pin holes in the propeller nut and propeller
shaft are not aligned, tighten the nut until they are
in line. Do not loosen.
Insert a new cotter pin through the propeller nut
and shaft. Bend its ends over the nut to secure the

TRIM TAB ADJUSTMENT

Improper trim tab adjustment can cause
difficult steering and loss of control.
A propeller will generate steering torque when the
propeller shaft is not running parallel to the water's
surface. The trim tab is adjustable to compensate
for this steering torque.
A single trim tab adjustment will relieve steering
effort under only one set of speed, outboard
angle, and load conditions. No single adjustment
can relieve steering effort under all speed, out-
board 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:
