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.

A protective motor mounting mechanism for motors and propellers mounted at the lower end of a shaft and in the water which includes a clamp for fastening the rotor mechanism to the motor shaft and a stator mounted to a fixed cross piece and a release lever portion. The rotor and stator cooperatively engage with other to maintain the shaft in a vertical position and place the motor and propeller in a force exerting condition in the water. A release lever is connected to the stator and is biased by a helical spring to and upward and connected position. The release lever is movable to a motor and stator disconnected position and the motor shaft, motor and propeller lifts out of the water. If the motor or propeller strike an object in the water while in the force exerting condition, the spring bias is overcome and the motor shaft, motor and propeller mechanism are removed from the water.
