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.
Trim angle greatly affects steering stability. 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 conditions.
When the motor is tilted beyond the maximum 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 planning attitude with the motor tilted beyond the maximum trim position.
If you operate the boat with the motor trimmed beyond the maximum trim position, the water intake holes may be above the water line, causing severe engine damage due to overheating.
Never operate the boat with the motor
trimmed beyond the maximum trim position.
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.
Top mount type
- Remove the cover (1).
- To increase the tension, turn the adjuster (B) clockwise. To decrease the tension, turn the adjuster (B) counterclockwise.
IDLE SPEED ADJUSTMENT
The idle speed has been factory adjusted between 650 – 750 r/min. in neutral.
If idle speed cannot be set within the specified range, contact your authorized Suzuki Marine Dealer.
SETTING OF TILT UPPER LIMIT POSITION
If the outboard motor contacts the motor well of the boat during full tilt up operation, the upper limit setting should be reset.
Perform this set-up after the current position setting has been canceled, as explained in the following procedure.
CANCELING THE TILT UPPER POSITION LIMIT SETTING
- If equipped with Keyless Start System:
Turn the Keyless Start System ON.
If not equipped with Keyless Start System:
Turn the ignition key to the “ON” position.
- Pull out the emergency stop switch lock plate.
- Make sure that remote control handle is in “NEUTRAL”.
- Top mount type
Using the throttle only function of the remote control box, move the control handle forward until the caution buzzer sounds one time.
Side mount type
Using the throttle only function of the remote control box, move the warm-up lever upward until the caution buzzer sounds one time.
Press the “UP” side of the PTT switch for three seconds and the buzzer will sound twice briefly indicating the setting has been canceled.
Return the throttle to the fully closed position.
SETTING THE TILT UPPER POSITION LIMIT
Press the “UP” side of the PTT switch so that the optimum full tilt up position for the boat can be obtained.
If equipped with Keyless Start System:
Turn the Keyless Start System ON.
If not equipped with Keyless Start System:
Turn the ignition key to the “ON” position.
Pull out the emergency stop switch lock plate.
Make sure that remote control handle is in “NEUTRAL”.
Top mount type
Using the throttle only function of the remote control box, move the control handle forward until the caution buzzer sounds one time.
Side mount type
Using the throttle only function of the remote control box, move the warm-up lever upward until the caution buzzer sounds one time.
Press the “UP” side of PTT switch three times within three seconds. The buzzer will sound one time briefly indicating the setting has been accepted.
Return the throttle to the fully closed position and install the lock plate on the emergency switch. Operate the full tilt up and full down operations several times by pressing the PTT switch and check that the setting of both the trim lower limit and tilt upper limit are properly set.
Setting of the tilt upper limit position will not prevent the outboard motor from tilting fully up and contacting the motor well if the motor’s lower unit hits an object at high speed. Such tilting could damage your motor and boat and injure the boat occupants.
Keep all occupants away from the motor when operating at high speed.
MOTOR COVER FASTENING ADJUSTMENT
If you feel motor cover fastening is loose or too tight when locking the levers, adjust as follows:
Loosen the bolt (1).
Adjust the position of bracket 2.
To increase the fastening, move the brackets to the direction (A). To decrease the fastening, move the brackets to the direction (B).
- Tighten the bolt.
CAUTION SYSTEM
The caution systems are designed to alert you to certain situations which may cause damage to your outboard motor.
Your outboard motor may become damaged if you rely on the Caution System to alert you to any malfunction that may occur or to give you an indication of the need for maintenance.
To avoid damage to your outboard motor, regularly inspect and maintain it.
Continuing to operate your outboard motor with the Caution System activated can result in severe damage to your outboard motor.
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.
INDICATOR CHECK
If equipped with Keyless Start System: Each time when the Keyless Start System is turned to ON state by turning the main switch to the “ON & OFF” position and then turning it back to the “PUSH START/STOP” position, four lamps – the REV LIMIT (1), the OIL (2), the TEMP (3) and the CHECK ENGINE (4) in the monitor-tachometer will light and the buzzer will also sound for the first two seconds.
