I have recently acquired an Alumacraft boat powered by an inboard engine. We believe the boat was built in 1956 or 1957, is 16 feet long with a twin cockpit. It is powered by a 4 cylinder inboard engine from a Crosley automobile with an AquaJet belt drive. It was acquired from a Minneapolis resident who had used the boat on Rainey Lake near International Falls MN for the last 35 years. We are looking for any information on this model; we think it is a prototype and there were only two built. I'll post pictures as soon as I figure out how.
