Abstract
An air cooled, belt drive and engine assembly mountable to the transom of small flat bottom boats in much the same manner as water cooled outboard engines with a lower foot 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 in contact with mud and vegetation. The engine mount includes tilt-up capability and pivotal horizontal steering. The propeller is capable of cutting through vegetation, provides propulsive thrust in mud and provides relatively fast boat speed in deep water.
