What might be the problem with my outboard? It is a 2003 Mercury 60hp, 2 stroke, outboard. Starts up right away, even after sitting for long periods, and 95% of the time it starts immediately on the water, but... every once in a while it just doesn't take and I fool with it for 3-5 minutes before it will start. I was wondering about this as I was playing pinball off of rocks the size of my house on the Big South Fork yesterday.
