Hello, I have a 1999 sea doo GTS I bought that needed a new MPEM. I replaced it with an aftermarket one from jetskiparts.com. I have also replaces all other electronics including coil pack, starter solenoid, voltage regulator and starter. It wants to turn over but the starter seems slow like a dead battery. I have been reading about the crankcase hydrolocking from oil, So I disconnected the oil hoses and let it drain. But I also read that if that happens there should be oil spitting out of the spark plug hole which it isn't. I even jump the starter with cables and it still seems to turn slow with the plugs out, and wont turn at all with the plugs in. Not sure what is left to do besides take it too a shop and pay the price. please help.
