Hello, I have a 1950s 16ft 56 inches wide Alumacraft boat. It has the removable aluminum cover in the front about 36 inches. It didn't have a title when I bought it, so when I got a title it says 2011. I don't see any factory numbers on it. There is an alumacraft tag on front seat that says Minneapolis MN. It does have the Aquaduct transom. I'm just wondering the the max Hp rating is. I'm thinking about putting a 1958 35hp Johnson Seahorse tiller motor on it. Thanks for reading.
