ABSTRACT:
A number of embodiments of small lightweight outboard motors adapted to be mounted on a watercraft that does not have a transom through a mounting bracket that spans the sides of the hull and is detachably affixed thereto. The outbaord motor is powered by small internal combustion engine that is contained within the lower unit and at least partially submerged beneath the body of water in which the watercraft is operating. Excess cooling of the engine is avoided by circulating at least a portion of the exhaust gases from the exhaust port around the exterior of the internal combustion engine. The engine is powered by a gaseous fuel contained under pressure in a container that is mounted on the mounting portion. Variations in placement and orientation of pressure regulators are disclosed so that fuel pressure will be constant regardless of the trim adjustment of the outboard motor. In addition, the connection between the outboard motor and the mounting bracket is such that the outboard motor may be easily swung from the suspended position in the water to an out-of-the-water position within the hull.
