Trim Tab Adjustment - Suzuki DF70A Owner's Manual

Trim range
 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
When the motor is tilted beyond the maxi-
mum trim position, the swivel bracket will
not have side support from the clamp
bracket and the tilt system will be unable
to cushion the engine if the lower unit
strikes an obstruction. This could lead to
occupant injury.
Do not operate the engine above 1500 r/
min or operate the boat in a planing atti-
tude with the motor tilted beyond the
maximum trim position.
16
If you operate the boat with the motor
trimmed beyond the maximum trim posi-
tion, the water intake holes may be above
the water line, causing severe engine
damage due to overheating.
Tilt range
Never operate the boat with the motor
trimmed beyond the maximum trim posi-
tion.

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
NOTICE
place.
