Outboard Powered Bicycle?

Wouldn’t it be great to find this gem under the tree? Something every motor enthusiast can appreciate! We don’t know much about it. We were sent these photos by a customer. The bike is in a museum and is apparently owned by Dave Williams from Norca, CA. The sign on the display says:

“FOUND IN A BARN! We don’t know if this water-cooled Evinrude bike was a factory prototype, or the product of someone’s imagination. Serial number indicates it is a 1936. It runs better than it looks.”

The mechanic that put this together was very creative. The stumbling blocks would of course be how to cool it, how to drive the bicycle wheel, and how to mount it to the bike.
