RE: Project... maybe...
I think theyre interesting doodles, if you run a surface drive its just gonna spin out, i would recomend a drive like the crackerboxes have. parallel to the bottom fo the boat but the prop if submerged. Or if you use a straight shaft, stick it out the bottom but have it stop after the transom but have maybe a cm of water between the top of the water and the boat and the prop if you understand what im saying.
