    Need help with Sea-Doo Sportster

    Have recently acquired An "03 Sea-Doo Sportster with the 951.2CC engine. Ran well initially but now will not run past half throttle or above 5,500 RPM. Fuel is pretty fresh with Sta-bil in it, fresh Sea-Doo oil, engine has low hours and based on the overall condition of the boat, was lightly used. Have replaced the Rectifier/voltage regulator (not sure if that's what its called) but that didn't help. Would appreciate any help in figuring out what to do next. I'm told that this engine is a very complex item and I'm probably not the best one to be fooling with it but I'm hoping it may be something fairly simple that I might be overlooking. Thanks in advance for any help or suggestions.

    welcome,
    most likely the carbs need to be cleaned/rebuilt.

    You will get far better answers if you post your questions (pictures help) in the sea doo 2-stroke section.

    Thanks. Being new to the site, I had wondered if I posted on the right forum. Thanks again. This particular engine uses a high pressure fuel injection and looks like nothing I've ever seen before.

    No Sir, the 2003 Sportster is a carb'ed 951. (947cc) http://partsfinder.onlinemicrofiche....=0-FUEL-SYSTEM

    It sounds like you have is a 2004 Sportster LE DI (951 Direct Injection) http://partsfinder.onlinemicrofiche....=0-FUEL-SYSTEM

    Sorry, I have no experience with DI.

    Couple things I'd try would be change the fuel filter and the water separator filter.
