X ADJUSTMENTS
ADJUSTMENTS Idle RPM in Gear The idle RPM in gear setting can be adjusted, if desired, to provide more idle control, steering, and quietness in certain applications. IMPORTANT: Only your Dealer can adjust the idle RPM in gear setting.
Trim Tab
WARNING Improper trim tab adjustment can cause difficult steering. 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 relieve steering effort under only one set of speed, outboard angle and load conditions. No single adjustment can relieve steering effort under all speed, outboard 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 outboard 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 35-40 ft. lbs. (47-54 N·m). Test the boat and, if needed, repeat the procedure until steering effort is as equal as possible. High outboard installations — The trim tab might be above the water when the outboard is trimmed out. Steering effort might increase. Steering effort will be reduced if you trim the outboard in and submerge the trim tab.
