Trim Tab Adjustment - Suzuki DF25 Manuel Du Propriétaire

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.
 WARNING
If you operate the motor with the tilt pin
removed, you may not be able to control
steering as expected.
Do not operate the motor with the tilt pin
removed.

TRIM TAB ADJUSTMENT

This adjustment is used to compensate for the
possible tendency of your boat to veer slightly
to port or starboard. This tendency could be
due to such things as propeller torque, motor
mounting position, etc.
To adjust the trim tab:
1. Loosen the bolt A that holds the trim tab in
place.
