1998 Challenger 1800. Bought this boat in 2001 and it ran great for a few months. Then the problem started, one engine will get to full rpms fine, and the other sticks at aprox 3500. The weird thing is that it's not always the same engine that sticks. sometimes the left would run and right would stick and the next day it might be the other way around. It's been to 3 different seadoo dealers and they all said they fixed it and lake tested, which turned out to be bs. The last one rebuilt the carbs and said compression was fine. That was 6 years ago, boat has been parked in my shop building in the corner since. Last weekend i decided to take it out just to see if maybe a spider fixed it while sitting, still does the same thing, I would like to fix it so i can sell it to get it out of the way. i searched around and found some threads on the rpms sticking but nothing about it alternating engines. any help would be great

Welcome to the seadoo forum. It could be the throttle safety switch in the control assy. It seems strange it would be alternating...to get to the switch remove the 4 screws and the square plastic plate. Then 4 more screws under the plate. I would spray down the screws as they get corroded from where they set. Lift out the controls. In the middle of the control is a small micro switch that sticks sometimes. It has a single wire going to it. See if its sticking.

Finally got some time to check this out. There is a switch below the Forward and Reverse lever that has 2 wires going to it, a black and a blue, that switch seems to work fine. Don't know if its ok or not but i hooked up water hoses to it and put it in gear and laid down on the throttles, they seemed to run fine that way.
