Re: Age This Boat
This is interesting.
I don't think it's a Alumacraft. It doesn't have the style of a Alumacraft boat that I've ever seen before. Along with the differences I posted above, the bottom edge of the transom is square instead of round, the oarlock brackets are mounted on the gunwale instead of the sides and it doesn't have hull runners on the outside bottom of the boat. It does have similar seats though.
There isn't any wood on the transom, for strength and to give it thickness to mount a motor, unless it was removed? Maybe someone just put a Alumacraft tag on the bow casting? You say you are working on the boat.
Only the manufacturer would be able to relate information on the brace stampings. All I can say is to call or email Sue Prax at Alumacraft and give your information. Phone 507-931-1050 or on the Alumactaft web site, Contact Information page, you can email. If no success at Alumacraft, maybe post what you have on the Boat Topics and Questions forum. More members will see the boat and maybe can give help.
