Trim Tab Adjustment
Propeller steering torque will cause the boat to pull in one direction. Steering
torque results from the outboard not being tilted so the propeller shaft is parallel
to the water surface. The trim tab can help compensate for this steering torque
in many cases and can be adjusted within limits to reduce any unequal steering
effort.
• Operate the boat at normal cruising speed with the outboard set at the
desired operating angle position. Turn the boat left and right and note the
direction the boat turns more easily.
• If adjustment is necessary, loosen the trim tab bolt and make small
adjustments at a time.
• After adjustment, securely tighten the trim tab bolt.
NOTE: Check for looseness of the bolt and the trim tab at regular intervals. Due
to corrosion, the trim tab will wear down over time.
IMPORTANT: The trim tab also acts as an anode to prevent galvanic corrosion.
Do not apply any paint, grease, or other material to the surface of the trim tab.
NOTE: Trim tab adjustment will have little effect reducing steering torque if the
outboard is installed with the anti‑ventilation plate approximately 50 mm (2 in.)
or more above the boat bottom.
The trim tab is located under the anti‑ventilation plate.
• If the boat steers toward the left, set the trim tab in the direction of B.
