About two sessions ago I noticed that I was not getting the same top speeds I was previously getting. It went from about 61 mph to 55 mph. I also notice after ridding for a short time there seemed to be more then normal amounts of exhaust. With further inspection of the overall craft I noticed that the spout near the front of the ski was not shooting out a strong stream of water as it used to. I am assuming that the engine is running too hot and is burning oil. Please tell me there is any easy fix that doesn't involve the dealer.
