I have access to two running Kawasaki supersport jetskis. The hulls are toast, but the engines are fine. My rough plan is to fit the propellor shaft to a lawnmower rear diff, and fab up a frame around it. Other than retrofitting the cooling system to a radiator, what else do I need to look out for in using a jetski engine? And can a mower diff handle the 75 rated horsepower or should I look into an ATV diff?
