I just recently purchased a 94 Wave Runner III. I seemed to start fine and run but when we got it in to the water, the problems set in. First it starts fine and idles fine. It just seems like its struggling to accelerate. I can feather the throttle and it starts to pick up speed and then it seems to just drowned. No power. I feather the throttle a little and she seems to want to go but just can't sustain any speed. Can anyone tell me what the problem might.
