Abstract
A watercraft includes a stern flotation compartment. The hull is carved out underneath the gunwales to admit a vertical cylindrical sleeve extending through the flotation compartment from top to bottom, and sealed top and bottom. A studded vertical mounting tube carrying an electric motor fits within a slotted cylindrical steering tube; the latter is carried on rotatable bearings affixed to the vertical cylindrical sleeve. A steering assembly is affixed to the slotted cylindrical steering tube and a guide tube fits closely within the vertical mounting tube. An electrical power cable is connected to the electric motor and a retraction assembly is affixed to the electric motor.
