Seadoo buddy; enough with the "wishful thinking"..lol
Hey jammyjam; i had that same issue, and it was the entire mpem(computer, brain, etc)....so, jumping the solenoid and it cranking can mean a few things... I was lucky to have a spare $400 MPEM laying around...
so, BEFORE you go spending tons of cash on a starter, etc... just MAKE sure that's what it is...even if you need a local mechanic off craigslist to diagnose it for like $50...
i replaced a few parts before i got it going...thats only cuz i had them laying around...
