I have a 115hp merc 1972 ser# 3370185, I have order a gasket kit that dose have the exhaust plate gaskets for the upper & lower plate for the exhaust tube. There are gaskets in the kit but not for my unit. I have talked to sierra tech & sent them pic's but they could not find the gaskets I'm looking for. (This is the sort end of the story) I'm sure ther are gaskets out there so if you have any thoughts clue me thanks
