go to New Jet Ski Parts and Used Jetski Parts - Jetskiparts.com and look up the breakdowns on both ski's. this might give you a idea if they will work or not. Don't know if motor mounts are the same or not? and how the electrical harness will work switching them around, I would think you could do it but better check it out to be sure, hate to see you buy and engine that you can't swap out.
No. the power valve motor wont fit in that ski. Dont know why you would want to do it anyway. But if you did do it, you would have to change the mounting points, also make them lower, get custom mounts. Then the carbs wont fit in and then you have NO CHANCE of getting the exhaust in.
