Okay, I'll try to describe it.
I have an 11' plywood rowboat that has a transom not capable of holding an outboard(not designed for it). I have an old outboard lower unit, which I will try to mount in the floor by the cavitation plate. Steering will be by an independent rudder. I have a Briggs lawnmower motor(w/ electric start!) that I will mount above the lower unit. I will also have to add floatation.
Weird enough for ya?
