My jet ski hasn't been out in 4 years but she is in legit like perfect condition. I had the battery and starter replaced at the beginning of the year. I took it out yesterday and it was reving up to 3600 and back to like 1800 while in idle. then wouldn't really take off when given gas it would Rev but not much would happen. it sounds like I sucked something up but would that make it Rev up and down without giving it gas. please help.
