Step 1: ADJUSTMENTS
TRIM ANGLE ADJUSTMENT
To help maintain steering stability and good performance, always maintain the proper trim angle as shown in the illustration. The appropriate trim angle varies depending on the combination of the boat, engine, and propeller, as well as operating conditions.
Make a test run in the boat to determine if the trim angle needs to be adjusted. Adjust the trim angle using the Power Trim and Tilt system.
Refer to the POWER TRIM AND TILT section.
If you still cannot achieve good performance, there may be a problem with engine mounting height. Consult your dealer for assistance.


• If the trim angle is too small, the boat may “plow” or “bow steer”, causing instability. If the trim angle is too large, steering control may be lost, the boat may “chine walk” from side to side or “porpoise” up and down, all of which may cause occupants to be thrown overboard.
• Do not operate the engine above 1500 r/min or operate the boat in a planing attitude with the engine beyond the maximum trim position (in other words, in a tilt position). In a tilt 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. In addition, beyond the maximum trim position, the water intake holes may be above the water line, resulting in severe engine damage from overheating.
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:
- Loosen the bolt (A) that holds the trim tab in place.

- 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 starboard side.

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 (A) clockwise. To decrease the tension, turn the adjuster counterclockwise.

When adjusting the tension of the remote control handle, consult your authorized Suzuki Marine Dealer.
IDLE SPEED ADJUSTMENT
The idle speed has been factory adjusted be tween 625 – 675 r/min. in neutral.
If idle speed cannot be set within the specified range, contact your authorized Suzuki Marine Dealer.
MOTOR COVER FASTENING ADJUSTMENT
If you feel motor cover fastening is loose or too tight when locking the levers, adjust as follows:
Loosen the bolts (1), (2) and (3).
Adjust the position of brackets (4), (5) and (6). To increase the fastening, move the brackets to the direction (A). To decrease the fastening, move the brackets to the direction (B).
Tighten the bolts.

Step 2: CAUTION SYSTEM
The caution systems are designed to alert you to certain situations which may cause damage to your outboard motor.
• Do not rely on the Caution System to alert you to any malfunction which may occur or to give you an indication of the need for maintenance. To prevent damage to your outboard motor, it is essential to regularly inspect and maintain it.
• If the Caution System activates while you are operating your outboard motor, stop the motor as soon as possible and correct the problem or consult your authorized Suzuki Marine Dealer for assistance. Continuing to operate the motor with the Caution System activated can result in severe motor damage.
INDICATOR CHECK
Each time the ignition key is turned to the “ON” position, four lamps – the REV LIMIT (1), the OIL (2), the TEMP (3) and the CHECK ENGINE (4) in the monitor-tachometer will light briefly and the buzzer will also sound for the first two seconds, regardless of the motor conditions.
For the next three seconds, the monitor-tachometer will indicate the total motor operating hours by means of the lamp flashing and needle indicating.
After this brief check period, the monitor-tachometer will return to their stand-by mode and will only respond to motor conditions requiring a caution alert.
