ABSTRACT:
A propulsion system for a boat utilizing two similar propulsion devices carried in a spaced apart relationship. Each device includes an electric motor, a propeller shaft and a propeller, and the two devices are supported on the extending ends of a yoke spanning the top of the boat to which the system is secured. A cowl substantially encircles each propeller and propeller shaft, and the two propulsion devices are rigidly secured to the yoke so that no rotation of either can take place. A control device regulates the total current passing through the propulsion devices, the direction of rotation of the propulsion devices, and the current passing to each propulsion device to determine the speed and direction of the boat.
