Countless things wrong with my sea doo, Please help?

first, get the water/fuel out of the tank. install a good fuel/water separating filter with a clear bowl(like racor),install a battery disconnect switch and a small on board charger. if you have run the engines on fuel/water you will need to rebuild the carbs most likely. i like to use "sea foam" fuel treatment. you can figure about 22 gph fuel burn
