I have an 04 Launch SSV with the Assult Indmar engine. Sometimes the motor seems to idle high like at 1500 RPM, which is about 900 RPM too much. If I disengage the prop and rev the engine, it will drop down to normal, or if I turn the motor off and back on it will be normal. It does not do it all the time, and it is not just when the motor is cold or hot. The timing varies. Any idea what the cause of this might be? I know the motor is computer controlled, so I am a bit unsure.

Many thanks
