    Engine Swap

    For the record, I am not in the process nor have I considered swapping my engine but has anyone tried swapping the 4-tec motor with anything else in these seadoo hulls and if so, what problems were associated with this??

    Wish I had a extra Suzuki Hayabusa motor sitting around. They pump out over 160 HP without turbo or supercharger. Oh and they run just shy of 11000 rpms.

    Would it work though??

    Dont know. I am sure somebody could do it. And it was built to run on 87 octane. Toss a super charger on, it's pretty normal to get them well over 200 hp. Guys have daily divers that put up 500 plus hp. Set the motor up to run 8000 rpm's and the torque would be crazy.

    I think 11k rpms would be almost useless in the water. if you had a prop pitched to use the R's it would accelerate dog poo slow.

    Note the post above says gear to bring the motor to 8000rpm's. That would giving off crazy torque numbers.

    And this is just an idea that I cant afford. I have to explore the stock motor yet.
