It's been fine all spring but when I pushed it up to 11 knots, it started hesitating, and did not stop (hesitating, that is). No matter what speed, or anything else I tried, including switching tanks, it would lose power in fits and starts - as if one of the cylinders were dropping out. Never slowed or sped up for longer than a second at a time. I could see the tachometer ticking up and down, and feel the boat lurching slightly. Did it all the way back to the dock.
The hesitation is oddly consistent, never getting better or worse, not changing with throttle, and never dying, even in idle.
I'll check the plugs, the filter, the oil level. Aaaaaand it could be the last year's gas too.
But any other suggestions, things I should check while I'm under the hood?
