Been reading alot on here trying to learn about my new toy, when ive taken it to the lake one engine will run perfectly and the other one will for a few minutes and then it will not go over 3500rpm.. checked and cleaned carbs, took it back to lake the engine that wouldnt run, runs great, but now the other one is doing the same (not getting above 3500rpm) .. Fuel gauge and speedo dont work but both tacks do...no beeps at all, think buzzer might be bad.. As for the MPEM, seen lotsa post from seadoosnipe saying MPEM was not used until 1996 but my shop manual says it has a MPEM..so does that mean it has the DESS lanyard and could this be making one engine run bad? Cant get both engines to run good at the same time..and it goes from one side to the other.. really blowing my mind..this is the frist PWC ive owned, Got it cheap cause no one else could get it running..I at least got one engine to run..hahaha.. Thanks to all who post on this forum .. its been a lota help
