What to do if my Suzuki Outboard Motor engine speed will not increase?
If the engine speed of your Suzuki Outboard Motor won't increase, consider these potential causes: * Check if the propeller is damaged or not clean. * Ensure the propeller is properly selected. * Verify the outboard motor is correctly installed and the trim angle is properly adjusted. * See if the spark plug is fouled or incorrectly selected. * Check for a kinked or pinched fuel hose, or a clogged fuel filter. * The fuel might be deteriorated, or the fuel pump might have failed. * The ignition system or electronic throttle system might be faulty. * Too much cargo on the boat. * Water in the boat. * Bottom of boat is not clean or damaged.
Why will the shift operation not be activated on my Suzuki DF150AP Outboard Motor?
If the shift operation of your Suzuki Outboard Motor will not be activated, it could be that the electronic shift control system has failed.
Why doesn't the Keyless Start System turn OFF on my Suzuki Outboard Motor?
If the Keyless Start System on your Suzuki Outboard Motor doesn't turn OFF even when the main switch is operated, check for loose electric wiring connections. A main panel failure could also be the cause.
What to do if the Keyless Start System does not turn ON on my Suzuki DF150AP (error sound heard)?
If the Keyless Start System on your Suzuki Outboard Motor doesn't turn ON, and you DO hear the error sound (five short buzzer beeps), it could be due to several reasons: The key-fob might be outside the operating range, have a dead battery, or be in OFF mode. The key-fob might not be authenticated, or there could be communication failure due to strong radio wave or noise. Check for electric wiring connection failure between the keyless control unit and the outboard motor, or an authentication error between them. An abnormality in the electronic control system of the engine may also be the cause.
What could cause the propeller of my Suzuki DF150AP not to rotate?
