I have a 1993 Waverunner 3 650, the last time I took it out it was running fine then it lost power, I cut it off turned it back on and it starts fine, idles fine and goes up to 1/4 throttle, after 1/4 throttle it just revs and doesn't go any faster... it is almost like it kicks into a neutral (i know it doesn't have one but that is how it acts). Do any of you have any idea what the problem might be. I got the ski last summer and took it out maybe 5 times never changed the plugs and never cleaned the carb. Any help is greatly appreciated

Check the water inlet on the bottom of the ski. Sometimes debris will enter there and entangle the inpeller. That can cause what you are describing. Just a thought.

Did you figure out what the problem was? I have the same issue. Thanks!
