    similar to it but that one is full blown race motor but i have same set up
    runs on 91 octane pump gas the one in the pics is Twin - 235 HP
    if ya add turbo to it it will go up towards to 500+ hp just like the one in my avatar ..

    Re: stuffing a snowmobile motor in a jetski ?

    that shouldnt be a problem at all. except.... i know the pipe on my sled is huge! i dont know much about the new ones. i would imagine they have made them smaller and better shaped from the sleds in 1980. but will the exhaust fit in there? and will you be able to set it up to exit the hull? you will probably have to attach some more metal pipe to it to route it outside the hull. but i really dont know becuase i dont know how the pipe is set up on that sled

    Re: stuffing a snowmobile motor in a jetski ?

    LOL well for exhaust system its still huge .. long like in J shape
    i was thiking of shortening the pipe like half pipe sorta thing
    and the route it like sx jetski
    attondeck.. you should check out my 400+ hp sled its in my avatar and in my photoalbum
    and yes its turboed boosted at 7 psi i can go up to 10's then that means ill have to run avi gas fuel to run it cleanly itll bump up to 430+ hp

    so rear exhaust. yeah that might work. the outlet couldnt be as small as the stock sx is though. that would probably be too restrictive.

    that engine cant be much bigger than a 550's. the carbs may not fit like that. and USCG will want f/a s on them. so if you can somehow make a 90 degree intake mani to face them straight up you should be good. exhaust will take some good hull mods.
