ADJUSTMENTS
Trim Tab
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.
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.
Tighten the trim tab screw to a torque of 11 to 15 ft.
lbs. (15 to 20 N·m).
Test the boat and, if needed, repeat the procedure
until steering effort is as equal as possible.
High motor installations — The trim tab might
be above the water when the motor is trimmed out.
Steering effort might increase. Steering effort will
be reduced if you trim the motor in and submerge
the trim tab.
IMPORTANT: If outboard is installed higher than
normal (anti ventilation plate out of the water), re-
move auxiliary water inlet screen (in front of the trim
tab). Install plate, P/N 5031618, with screws saved,
to prevent overheating and engine damage.

Throttle Friction
Adjust throttle friction on your remote control to
maintain its position and prevent unwanted throttle
“creep” under normal operating conditions.
To adjust, start engine and move control handle
into FORWARD throttle range. While underway,
turn adjustment knob clockwise to increase friction.
The friction adjustment is effective only in the
FORWARD throttle range.
1. Throttle friction control
See your Dealer for throttle friction adjustments on
your specific remote control.
WARNING
Improper trim tab adjustment can cause dif-
ficult steering.
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.
