Yesterday was out boat was running fine. Ran around a bit then stopped @ a local watering hole. No issues to this point. Got back to the boat smelled gas found the fuel filter came loose, my fault for not checking everthing after last run. Anyway fied and cleaned up and waited a while to be safe before starting. Now the issue after ideling back down the river I put the boat in neautral and the idle ran up to about 17-1800 RPM????? Shut it down cuz I sure as hell was not going to shift like this. Fired it back up and it was fine. Went back out on the lake and ran it, after slowing down same thing, fast idle. WTF? shut down fired again and fine. If I idle around it's ok but once I run it and slow back down it happens. Any ideas??????? Thanks Jason
