Abstract
A belt driven outboard drive and engine assembly mountable to the transom of small flat bottom boats in much the same manner as water-cooled outboard engines. The assembly includes a lower drive shaft assembly that does not extend below the bottom of the boat, but extends a sufficient distance behind the boat to insure the proper angle of attack when the propeller is positioned for contact with mud and vegetation. The engine-mounting bracket includes a unique dual pivot tilt-up and tilt-down capability, an incremental positioner and a pivotal horizontal steering handle. The propeller is capable of cutting through vegetation, provides propulsive thrust in mud and provides relatively fast boat speed in deep water. The assembly further includes a clutch and reverse drive electric motor.
