After winterizing and sitting up all winter I decided to take the boat out for a test run this past weekend, after filling the tank up with fresh non ethonol gas from a store that usually sales a lot of gas to boat owners because it's close to the launch. the boat seemed to crank fine and sounded ok at idle, so I gave it a little more throttle to try and plane out and everything seemed to be going fine until the boat "fell on its face" after this happened it was like the boat would never reach over half throttle even when the throttle was all the way down. A check engine light did come on during this. I'm no mechanic by any means so any useful tips or hints would be very much appreciated. Thanks
