Susquehanna Air Motors SAMI 4 Outboard Fan Motor

I purchased this along with a 1969 DeSoto 14" Jon Boat for $200 at a local auction. It ran well until the wood blade stated to split. I sold motor only last month for $250 and bought a '65 Johnson 9.5 with homemade rock guard made from old pitchfork. I live on a river so always buying vintage fishing and boating collectibles.
