This past weekend I noticed gas leaking into the water coming over the swim platform on my 99 Santera when the boat was running in neutral or idle? Quite a bit of gas actually. In the slip there was about a 6' ring of gas behind the boat. Because it was coming over the swim deck I figure it is coming from the exhaust? Can anyone tell me what might cause this or what could be done to fix it. It's fuel injected and I'm running No Ethanol Premium gas. Any tips or advice would be very much appreciated. Thanks!
