I have a 1995 seadoo speedster with twin 657x. The mpem has went out. The seadoo will start but will not rev 3500 rmp. I have change Netual switch and the Rectifiers out. The boat will start forward and the beeper is not working. Does anyone have a wiring diagram to put two mpem in place one the one?

I wonder if the MPEM from the 96 Speedster will work? IF the problem is in the MPEM. I have the whole gray box with coils, rectifiers wiring and main plug. I just finished restoring a 1996 Speedster and bought a MPEM, box and all which I installed in the Speedster. I thought it was an MPEM issue but it was a wire going into the Port engine that was bad. I paid $500 for the box I installed so I still have the original that worked fine. Don't know if that would help you. I've seen these things listed for $1200 which is insane.
