    I do not believe it has been done yet. I think it would be a tight squeeze to get it in there.

    The first thing you can do to F-up a Yamaha is to put a Sea-Doo motor in it. Just my opinion.

    After you replace the ceramic washers, maybe it will last a while.

    It would turn a monster prop.

    you are nutz dude!!! is that why you have all those cylinders on ebay???

    Joe and mark were asking about it when I had my 99 apart. not sure what the verdict was. It may not fit because the doo motor sits crooked, almost like a V, and it is off center. the gp engine compartment is tall enough, but fairly narrow.

    If it fits, do you think the extra weight of the engine would help the porpoising any ??

    Like they say, if you put your mind on something you''ll get it done. But on the other hand, I think it will be a very tight fit. As the intake of the RXP is huge with the fuelinjector. I don't even know if somebody placed an GPR engine in an gp hull. I don't think the exhaust won't fit under the seat.
    But it will be a nice project to see. Keep us posted.
