It IS quite confusing though, I had to take out a normal and a reverse (model airplane) prop to check if I wasn't talking nonsense!

If you install a prop back-to-front you here a prop still thrusts in the same direction, just less efficiently. If you had one "normal" and one "reverse" prop installed you'd get about 25% net thrust, and a walrus would barely get to a fast trot with that sort of thrust.
