    Which Polaris Snowmobile PTO End Crank Web will fit the 780 SL crank?

    Hulk members,

    Curious to know if anyone can inform me of a model/year of a Polaris Snowmobile PTO-end crank web that would fit a Polaris 780 SL PWC engine's crankshaft. I want to run it with a clutch (for a different application on land). I want to use an electronic water pump (from Jegs.com) and block-off the exhaust manifold waterjackets from the headpipe and expansion chamber's waterjacket for closed-loop cooling... I have the engine and the ability to change it over, just not the knowledge of which PTO Crank web to get.

    I intend to use the engine to construct a wakeboard winch. If you are curious, look up 'grinch winch' in Google. My design would be the 'grinch winch' on steriods with a shot of Jack Daniels.

    Thanks!
    -Gringo

    You would have to check out the stroke to be the same. But my guess would be the 600 or 650 or maybe the XLT. Maybe check with Sharps, sure they would know.

    Look into the the Storm 750 & 800 motors, these were very similar to the fuji watercraft engines.
