Took my new to me Wake out today, first time on the water. Boat has 82 hours, fresh SC rebuild and runs great on the trailer. Unloaded and it ran great, idled out past no wake zone and took off. It was hauling the mail then just fell on its face. I limped it back, seemed to be running on 2 cylinders. It would try to clear up and run a couple of times. Could this be as simple as spark plugs? They looked ok so I don't know if this is the problem. I started it out of the water again and it sounded horrible. Let me know your thoughts, I'll get some plugs and try again next weekend.
