    Can a STX-15F be supercharged?

    Is the 1500cc engine in the 310 the same as the STX without a supercharger? If so, is it possible add a supercharger to one?

    Also, even if you could add a supercharger, would the hull allow higher speeds?

    Thanks,

    Mark

    There is a belt driven kit that was available before the ultras came out. I don't remember the specifics, but it was over $3,000 for the kit. It ran 12F pistons and straight race fuel. I've never seen one for sale second hand. No telling what happened to them.

    There were some Vortec 15F's out there and they were 80 mph+. 330+ hp Riva kit was around also.

    Might be cheaper to put a 300 motor in it and you can run pump gas lol.

    Wont fit with the 300 exhaust manifold.... now modify a 300 top deck to fit and you'd have what we've been asking for, for a long time

    Might be cheaper to sell it and buy a new supercharged ski....
