In the Old Outboard Book, there are 3 diffferent brands of OB that used an airplane style prop to push a small boat Aerothrust, Air-boy, and Airdrive. The airboat motors I've seen are pretty big with full size airplane props and look like serious business, but these were evidently little air-cooled low hp kickers that you could stick on the back of your boat and go fishing. Has anyone ever heard of these or seen one? Did they actually push a boat. Doesn't seem like a small prop would push enough air to move a boat very well. Would be tempting to get a chainsaw/weedeater type motor and mount a prop but I wonder if this would do anything more than sit there and make noise.
