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

that holds the trim tab in

place.

2. If the boat tends to veer to port, move the

rear end of the trim tab toward the port side.
If the boat tends to veer to starboard, move
the rear end of the trim tab toward the star-
board side.

3. Tighten the bolt that holds the trim tab in

place.

After adjusting the trim tab, check to see if the
boat still tends to veer to one side. If necessary,
readjust the trim tab.

THROTTLE TENSION ADJUSTMENT

The tension of the remote control handle can be
adjusted according to your preference. To
increase the tension, turn the adjuster

clock-

wise. To decrease the tension, turn the adjuster
counterclockwise.

NOTE:

Top mount type

When adjusting the tension of the remote con-
trol handle, consult your authorized Suzuki
Marine Dealer.

IDLE SPEED ADJUSTMENT

The idle speed has been factory adjusted
between 750 – 850 r/min. in neutral.

NOTE:
If idle speed cannot be set within the specified
range, contact your authorized Suzuki Marine
Dealer.
