TRIM ANGLE ADJUSTMENT
To help maintain steering stability and good
performance, always maintain the proper trim
angle as shown in the illustration. The appropri-
ate trim angle varies depending on the combi-
nation of the boat, engine, and propeller, as well
as operating conditions.
•
Trim angle too large (Boat tends to “porpoise”)
• Trim angle too small (Boat tends to “plow”)
• Proper trim angle

trim angle needs to be adjusted.
To adjust the trim angle:
1. Hold the motor in the fully tilted up position.
(Refer to TILT UP LOCK ARM section.)
2. Reposition the tilt pin A in the desired holes.
3. Lower the motor back down.
To lower the bow, move the pin towards the
boat. To raise the bow, move the pin away from
the boat.
