Any thing is possible. but it is not allways feasable. the cost would not be worth it. but if you are determined I know where a 4 stroke pontiac 455 is that has some awsome torque. If you could keep it afloat I am sure it would have all the horse power you would ever want out of a ski. I am sure you would need a beter pump to recieve all the power though. lol :cheers::rofl:
