Hi, I recently got a very nice condition Johnson Sea-horse. Guy Said it was a 5hp but I’m not sure on the year.1176452E-095A-4A54-83E4-A9C9316A253F.jpg

Looks to be about 1953 or older.-----Super nice running ( no noisy reed valves ) on them.----Remove lower cowl to find model #-----HD models were 2.5 HP.----TD were 5 HP direct drive.-----TN were 5 HP with neutral shift ( wrap spring ) dive.
 
Its a TD-20. I found this chart online which would mean mine is a 1941 I think? It was also seized but I put some marvel mystery oil down the cylinder and it unseized. It does grind at a part of the stroke so I stopped right then. I think it’s some junk on the cylinder wall
 
????----Once again.----My information says 1949 to 1949 for a TD 20.----Make sure you use correct charts.----That MARVEL oil should fix it !!
