Oars and paddles are surface drives. That means you need to add Ogg the Caveman to your mfr list.
Paddlewheels are definitely surface drives.
Fulton makes the list, too.
Any early 3-point hydro makes a good case for a surfacing application.
Outboard race boats running extremely high X's are surfacing propulsion.
Back when I dragged outboards, there was a triple engined Evinrude monster cat with the skegs cut off the motors, extra short midsections, and the steering locked on center - used a single knife edged rudder to steer. Definitely a surfacing application.
I suppose we are limiting the discussion to stuff that looks like a prop hung waay out back on a shaft ??
If so, we still have to include those Chinese rice paddy boats with the 10 foot propshaft on a tiller...
What are the rules, guys ??
