[QUOTE="willholl79, post: 318027, member: 11981"] I just recently purchased a 1436 jet jon with a 500cc Yamaha Waverunner engine. With just me sitting in the back driving, it will jump on plane fairly quick but still has cavitation issues. With another person in the boat it won't get on plane. The boat was built by the previous owner using the cut out hull section of the wave runner grafted to the jon boat. It's not the neatest rig in the world, but I plan on reworking some areas, if I can get cavitation under control. This is my first experience with a "jet boat". I have had jet skis in the past. I am trying to figure out where to start with this issue. Is it the pump itself, weight, or angle/draft of the jet, not enough water in the intake, all of the above? Any help is appreciated. This is a great site! [/QUOTE]
