My husband and I recently bought two jet skis... one of which is a Yamaha (mine!). We got a great deal on it, bought from an older man (one owner) that had only put 38 hours on it. We've had it in the water for the last month and it has run like a champ. However, when my husband and some friends took it to the lake on Saturday it decided to act up. When he first put it in the water and cranked it up, they idled out of the no wake zone... got out of the zone, gave it some gas, and the engine didn't rev (maybe 4000rpms) and wouldn't run over 11-12 mph. Trolled back up to the dock, loaded it on the trailer, took it out of the water, gave it some gas and it revved up fine. Put it back in the water, trolled back out of the no-wake zone, gave it gas but it would only go to about 9000rpm and only about 40mph. It never would really go like it can and should. I've tried searching the forums and I've not had any luck with any answers. Any ideas?
(note: it would rev all of the way up in reverse)
