I have a 1990 Evinrude E115TLESB which has lost a piston due to head gasket failure. Rebuild cost outweighs what I would pay for a 1995 115 powerhead. Will this motor mate to my existing midsection? This is a repeat of my previous topic, I have removed the screaming capitalized text to tone it down. Thanks for any assistance offered. I have to make a choice today.
