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 small (Boat tends to “plow”)
•
Trim angle too large (Boat tends to “porpoise”)
• Proper trim angle
Make a test run in the boat to determine if the
trim angle needs to be adjusted.
To adjust the trim angle:
1. Lock the motor in the fully tilted up position.
(Refer to the 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.
After you have made an adjustment to the trim
angle, make another test run to make sure you
have adjusted it to the correct angle.
WARNING
Trim angle greatly affects steering stabil-
ity. If the trim angle is too small, the boat
may “plow” or “bow steer”. If the trim
angle is too large, the boat may “chine
walk” from side to side or “porpoise” up
and down. These conditions, which result
in loss of steering control, can cause
occupants to be thrown overboard.
Always maintain proper trim angle based
on the combination of your boat, engine,
and propeller, as well as operating condi-
tions.
