I picked up a what I think is a 1959 35 hp Johnson super seahorse. I believe it the 59 only because of the design of the top. I think the 35hp super seahorse was only available in 58-59. I can not find any numbers, I have looked in the common places. I did find a round chrome plate about size of a nickel. With the# 1969761. Using that # compleatly throughs off my idia of what it is.
