ABSTRACT:
A motor and a propeller for a canoe are mounted to be manually positioned either within a box over an opening through the bottom of the canoe or, for operation, below both the box and the hull of the canoe. The motor is connected to the box by a usual control shaft, the control shaft extending upwardly through a supporting member and a cover of the box. Resilient grommets about the shaft and polyethylene foam insulation of the supporting member dampen noise and vibration. The supporting member moves either upwardly or downwardly with the motor and in a downward position closes the bottom of the box to prevent eddy currents within the box.
