Well i gota boat. it's a '68 thompson, so the owner claim's. but, a sticker on the valve cover mention's '71. so, its go an omc 120 (GM 2.5). the guy ran it last year and over heated it and said a guy looked at and said it needed a top end. i'm assumeing the head is warped and leaking. don't know. it will turn over. rebuilding the motor shouldnt be a problem, as long as i can find part's. and now i turn to you guy's/girl's. i cant find any one who has parts for it. the farthest back i can find is '80's. so, anyone know some good site's to visit? thank's for the help.
