Mercury 40 4-Stroke User Manual

OUTBOARD INSTALLATION
87
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 inches) or more above the boat bottom.
Operate your boat at normal cruising speed, trimmed to the desired position. Turn your boat left and right
and note the direction the boat turns more easily.
If adjustment is necessary, loosen trim tab bolt and make small adjustments at a time. If the boat turns
more easily to the left, move the trailing edge of trim tab to the left. If the boat turns more easily to the
right move the trailing edge of trim tab to the right. Retighten bolt and retest.
Trim-In Stop Adjustment - Power Trim Models
If an adjustment is required to the trim-in stop, reposition the tilt stop pins in the desired holes. Tighten
the tilt stop pins to the specified torque.
