2008 RXT-X supercharged. Had the SC rebuilt and replaced just barely, and the seadoo isn't running well. It will start/idle just fine, but when you drive it, it acts like the learner's key is in or something...feels like there is less power and not supercharged. Then when we drive it harder and push it for about 20-30 secs, the seadoo will start to just choke up and the RPM's will start dropping like it is dying. The engine doesn't die, but it loses all power. Once I saw an "exhaust error" on the code screen when this happened. If we let it sit and idle for another 10-20 secs, it will start to rev and get power back, then you can ride it again...almost like it is clearing something out. If we just ride at about 50-60% capacity (ie. don't push it too hard and just putt around), then it will keep running for quite a while w/o the choking problem. Took it to a dealer, who has had it for 3 weeks and has not found the problem!!! The only thing they noticed is that when they put it in test tank that it performs better when the front plastic storage bin is removed. I'm having them change oil and plugs. Any other ideas or experience with this issue? My summer days are disappearing while these guys scratch their heads. I'm in Boise, ID if any of you know a better place to take these SeaDoos.
