I have a 1986 110hp vro bubble back. Ran great all day. All of the sudden I started it up, hit the gas full throttle, it stalled. Got it running but would hesitate. Seemed to be running rough at no wake speed. Thought fouled spark plugs. Changed them on the water. 1 out of 4 seemed a little wet. Still ran bad in the beginning, then it would rev up normally. Spark plug change had no effect. I'm thinkin 1 coil bad. Any input?
