No the 800 mod motor was a race built skidoo motor package to install into the 440mxzx. It's a twin
It's carbureted twin or single pipe configuration.
2004-2008 I believe

Sleds make peak power at ball park 8250rpm, most dont have a clutch engagement under 3500 rpm, the power/torque curve is not desirable for a ski application. If this were even close to a viable option Polaris, Yamaha and ski/seadoo would have been using shared watercraft/sled motors since he inception.
