    Thanks for getting back Chris, i purchased the Sierra 18-2684 and My 1957 Evinrude 18hp is model 15020 Serial# 27598 i haven’t taken the lower unit apart just yet but i wanted to be prepared in case the Sierra 18-2684 prop shaft seal is not the correct one. Thanks!

    So sorry did not see this!

    You are lucky. The 18-2684 should have the correct prop shaft seal for you. This kit will serve the 1957 18hp Evinrude above serial number 22000 as yours is. So that is good. If it were lower than serial number 22000, the prop shaft seal would not work. As there was an engineering change mid year 1957. Sierra does NOT make a seal kit for the ’51 to ’57 10 to 18hp OMCS, as they do NOT have a replacement for the 302495 oil seal.

    Hope this helps.
