I've built a prototype outboard bracket for PocketShip. (My nose is still eight feet in the air about adding an engine to such a nice little sailboat, but there you are.)
I don't have dimensioned drawings of the bracket yet, or photos of it mounted on the boat, but we did throw the assembly instructions up on our website:

Hope to have more complete instructions and photos once I get up the nerve to bolt the thing on my boat's transom. It's certainly elegant and strong and will be fine for a little Honda 4-stroke 2hp.
