Alright fellas, I bought a 99 seadoo challenger 1800 with the twin Rotax 787’s. Both engines start and run. The problem is with the right engine. It takes a little longer to start, and when it does it doesn’t have enough power to get the boat on plane like the left engine does, and the tack is showing 1.5k less than the left. It has good compression. I installed new spark plugs, new fuel pump, took the carburetors off the engine and rebuilt them. Any help would be appreciated, like I said both engines run, but the right engine just doesn’t have the same amount of power as the left.
