Hello everyone and thanks for accepting me. I am from Argentina and I have a Bermuda boat with Evinrude V4 115hp outboard motor from year 1976. I had a piston failure and a broken ring. I need to corroborate what measure it has of piston. What are the original and replacement diameter?

That info would be in a factory service manual. Hopefully someone on this site will come back with the info.

Original bore is 3.500".----Replacements are 3.520" / 3.530"

Need to replace all of them as the late model 76/77/78 had high ring pistons and very prone to fail....
