ok --newby to the thread--but half mech--got the boat & mtr this wknd knew it had a cyl down --head removed on bad side --bottom piston pitted bad ---didn't break any rings that i can observe--port side --I am doing whatever it takes to do it myself but am wondering what caused this to happen --head looks good--- have some what looks like gaulded aluminum on cylinder wall but looks like it may hone out --all other cyls cked at 100 psi on comp ck cold ---think i'm ok there---what happened to destroy the one piston?
