  • Remotely steered toy boat
    Patent number: 4048751
    Abstract: A drive for a remotely steerable toy boat includes a reversible motor, a propeller shaft and a propeller. A stationary deflector shield is disposed laterally of the propeller. When the propeller is driven in reverse, part of the stream of water delivered from the rear to front, relatively to the boat, is forced against the deflector. Consequently, the boat turns.
