Just launched last weekend and had a near disaster. My fairly new Merc four stroke 6hp outboard quit about 30 yards from the ramp in a high wind. We got pushed into the slips and into a couple boats with outboards tilted up. Yikes! I got some good scratches. The darn thing will run all day in neutral at high revs. But try and go anywhere, and it will quit. After a couple fast restarts we got it into my slip. I'm wondering if I got the vent on the tank all the way open? Bad spark plug or wire? It's only three years old. And after sitting all winter it started on the second pull! I just put in new gas too. And I always run it out of gas at the end of the day.
