I have a 2008 GTI 130 I was on the Lake running and all the sudden I heard a pop not a loud pop but the jet ski just slowed right down and then I went ahead and tried to move forward again. The engine sounded fine but I was getting a loss of power. Even though the RPM's got up to 7000 it felt like it was only running at about half the speed. I don't know if anyone else has had this happen to them but, I would appreciate any help you could give me not sure what to look for. I bought the ski about a week ago from somebody else. So I may have bought a headache, I hope not. Oh it also has 180 hours on the ski.
