    Re: 1991 Kawasaki 300SX engine swap

    I've read a couple posts from people putting a 550 into a 300sx. They used a 1/2" aluminum bars mounted to the hull, then drill and tap into the bar for the 550 mounts. This would work perfectly for larger engines with the 650 adapter plate.

    It was recommended that the bottom of the hull be reinforced with a few layers of fiberglass to prevent cracking in the hull, as the hull wasn't designed to handle the horsepower of the larger motors.

    If you're not crashing, then you're not trying!!!

    Ski situation in limbo!
