I had the boat out this weekend and out of no where the engine lost power. I could only rev the engine to 2,000 rpm's while in gear. Has anyone experienced this issue? Once getting the boat home and connecting the water muffs, the engine will start right away then die, it will stay running if I keep the engine at more than idle. I have ordered new spark plugs and a new fuel filter, waiting for them to arrive. What else should I be checking?
