    951 Questions

    I am not a Sea-doo expert so I need some help. What is the difference between
    the gray and white 951's? Can these pieces interchange? Some say 947 on the
    tag on top of the crankcase. Any help would be appreciated....

    951 and 947 are the same thing. The engine volume is 951cc and Rotax used to use a 7 in the last digit to denote a marine engine. Thus, Rotax rounded down and called it a 947.

    That said, I know the heads are the same between a white and a silver 947. I think the front cover and stator would interchange also, but I have no proof. The starter should be the same too.

    The cases and cylinder do not interchange and the pistons were different (well, the rings are different anyway, though they may interchange). That is, I do not think you can put a silver cylinder on white cases nor a white cylinder on silver cases. I also have reason to believe that the carbs were somehow different (just something I saw once, they may yet interchange).

    This is the little I know about the white engines so I hoped this helped.

    The exhaust is different too, it has less of a flat area than the silver motors pipe, and can be used on silver motors to make more power

    The pipe mount is also much less sturdy on the white motor vs the silver motor

    it isn't the pipe so much as the whole deal, pipe,exh manifold and the porting that came on the 97.5 makes the pkg. If you get your exh manifold professionaly ported and the pipe extruded honed it will be a difference.

    I had my pipe extruded honed once and it was amazing. Best 20 bucks I ever spent.

    No, if I remember right, she was from South Carolina.

    I am not sure how that would make your boat run faster but it sure felt good.
