I'm in the process of looking for a powerhead for my 1982 Mercury 18 hp model# 1018202, serial# 6043500. I was wondering if anybody knew what years are compatible? And I think the 18's and 25's are the same motor but not positive, so if anyone out there could give me a little insight into this it would be appreciated.

From what I'm seeing the 18's, 20's and 25's seem like they would work, just having trouble pinning down which years are compatible.
