js440 hull/650 sx
i have an 83 js440 hull and im about to pick up an 88 650 sx ski with a crack in the hull how hard would it be to swap the motors out and put the 650 into the 440?

read my thread... your biggest concerns should be adapter plates, pump efficiency, drive shaft to motor coupling, (remember that the throttle cable gets mounted to the intake manifold ... on a 650 its different... plus are you going to be going performance... you maybe need to re-jet the carbs... etc..
you have some work ahead of you but its quite doable.!
and if you need more info go here:
