ABSTRACT:
a propulsion and steering apparatus generally for a boat having a unitized construction comprising an engine, propeller, rudder and protective cage for the propeller, all mounted on a rotatable pylon adapted to be secured to the transom or other portions of the boat. A rudder is attached to the pylon and projects into the water to facilitate steering of the boat if the engine should die or be at idle speed. An ice break can be substituted for the rudder for use of the vehicle on snow and frozen water such as for ice fishing and rescue work. If desired, the apparatus can be mounted forwardly of the transom on transversely extending beams in the boat to provide a large open area that will be kept available for fishermen and equipment in the rear of the boat. The entire propulsion means is adaptable to be hinged to the mounting so it may be laid down to present a low profile for moving under bridges, storing in garages and while being transported on the highways.
