Check Engine Light

The red malfunction indicator Check Engine light is operated from an on-board computer that monitors the operation of your fuel, ignition and engine control systems. On some models, the Check Engine light should come on when the key is in the ON position and the engine is not running. This is a check to show you that it is working. If it does not come on at all, have it repaired by your MasterCraft dealer right away.

If it stays on or comes on while you are operating your boat the computer is indicating that you have a problem. You should take your boat to your MasterCraft dealer for immediate service.

Notice: If you continue to operate your boat with this light on, you could adversely affect the emission control systems on the engine. You could also experience poor fuel economy, and your engine may not run as smoothly. This could lead to costly repairs not covered by your warranty.

Should I leave the ignition switch ON?

Never leave the ignition switch in the RUN position without the engine running; this will prevent the natural discharge of the battery and result in damage to the starter solenoid.
