Aww man, that sucks, you should probably just buy a nre jetski from PowerSports360.com - Covering All Your Power Sports Needs. Na, jsut kidding. But you need to make sure that you have all the water out of the ski. Take out all the plugs and let the engine keep cranking to air everything out. After that spray some foggin oil in there to make sure it is still lubricated. Then run it one time. THe next time you run it change the spark plugs. If it is still not running right you will need to dig a little deeper, and that could get ugly. If you need anything, call the guys from PowerSports360.com - Covering All Your Power Sports Needs they are good.
