    OMC stringer thump sound from the rear.

    I have heard a thumping noise from the rear and I think I felt it too. It’s only happened 3 times and it happens fast enough to where I can’t pinpoint what’s really going on. Best I can describe it as is: The thump/feel feels like when you’re lowering/tilting the drive into position until you...

    OMC sterndrive not moving in gear.

    Finally took my 1984 sterndrive out today. First 10 minutes were fine at 4k rpm. Then it died and would stay moving at 1800-2K rpms. Anything above and it would shortly die in about 30 seconds. Figured it was a dirty carb. Parked the boat for a few hours and started going back to the dock and...
