Re: How did my outboard get holes in the pistons?
This motor has obviously been worked on before. Either the left end piston was replaced or the right two were replaced at one time. The holes in the center of the piston were not drilled by someone and I'd bet they do NOT go through the crown. If you look at the left piston (11 o'clock) you will see a similar hole. It is not unusual to see a hole in a piston -- it would be unusual to see those holes go all the way through however.
