    Is it possible for me to bolt a 657 or 720 engine into my 91 Seadoo.

    Physically, yes - but you need all the external bolt-ons to make it work - including the electronics.

    Would I be able to use the same carb intake, exhaust manifolds and flywheel. How about the rotary valve and oil pump? If I was to purchase lets say a 657 off you guy's would you take my 587 as core? The other problem is that my 587 has a crack in the lower rear crankcase due to a bigend rod bearing failure(probably could be welded)

    No, no, no, no, no and no. [img]tongue.gif[/img]

    We can weld holes and cracks as long as the damage is not to any mating surface.
