Title: Marine outboard electrical generator and assembly method

Abstract: A outboard marine electrical generator unit capable of installation on the transom of a marine vessel which provides an electrical generating unit for small and medium sized marine vessels. The invention thus provides an A/C and D/C electrical power source capable of providing electrical power for appliances, air conditioning units and other electrical loads, even while the primary propulsion system is off and the vessel is docked or at anchor. The electrical generator includes: (1) a housing, including upper and lower portions, generally having the external appearance of an outboard motor; (2) an internal combustion engine; (3) a permanent magnet electrical alternator, including a rotor and stator, and a cooling fan, mechanically connected to the engine crankshaft; (4) a carburetor assembly, including feedback control responsive to electrical load; (5) an inverter module, including pulse-width-modulation ("PWM") voltage regulation system and D/C-A/C inverter frequency regulation system; (6) an exhaust system terminating at the lower housing portion in a typically submerged location; (7) a fuel storage and delivery system, including either an internal and/or external fuel tank and a fuel pump; and (8) a transom mounting mechanism, preferably including a tilt feature.
