2007 x45 L18 crazy idle issues ???!!!
bought my first boat... 2007 x45 L18, 195 hours, first time out it ran fine, second time out when pulling it in to load up, the idle was revving to 1800-2000, and then once I revved it up in neutral it went back down to 7-800, (this happened 3 different times) today (the 3rd trip) the boat ran fine until we were about to load it up and it was doing the same things, revving up to 2000 and even 3000 at one point, then the CHK ENG display popped up, and the alarm was sounding, it had good oil pressure and temp was fine... then i noticed it wouldnt engage throttle, but it would pop into gear... even when in WOT position there was no gain in rpm... once i shut off the motor and restarted the throttle started working properly but idle speed was still all over the place... any ideas???
