I have a 97 XP, during the last ride I had it out my brother spilled it coming into the docks but flipped it upright the wrong way. I didn't know this til I took it to get winterized because I couldn't get it started... 3 months later. They told me the water in the engine more than likely has ruined the motor. Is there any kind of fix to do that may clean the "rust" out besides putting in a new motor? It's the 787.
