I have a Sea Doo 2009 230 Challenger 255 HP for sale but nobody will buy it with one engine not running. Beginning of May I have decided to sale the boat because I was not using it as much as in previous years. I was taking the boat to put it on the trailer, the boat was on a lift. I pull out from dock and went about 300 yards at idle speed and the one engine started to squeal. I immediately shutdown both engines. I then tried to start both engines, only one would start. The bad engine does not turn over (locked up). Looking for some ideas on the problem. Has 180 hours on it super charger was rebuild at dealer at 95 hours. Pump, super charger, engine??? How to diagnose the problem??
