View Full Version : Rough Idle

My boat has been sitting for about 5 months being started once a month and it is now idling rough until it reaches operating temperature. It's an 06 rtp-1 engine. Any ideas as to the cause?

Fouled plugs. If you just started it and didnt get it up to operating temp it will foul the plugs, especially if you are running a ethanol blended fuel.
