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.

[ What is claimed is:] [1.]1. An electrical generator for installation on a marine vessel, said electrical generator comprising:an internal combustion engine having a projecting crankshaft, an air intake for providing combustion air to said engine, and an exhaust system including an exhaust outlet for discharging engine exhaust; said internal combustion engine constructed to be securely mounted to the marine vessel such that said air intake is in fluid communication with the ambient atmosphere and said exhaust outlet is disposed below the vessel's waterline;a permanent magnet alternator mechanically connected to said crankshaft for producing electrical current, said permanent magnet alternator includinga stator mechanically connected to said internal combustion engine, anda permanent magnet rotor connected to said crankshaft for rotation with respect to said stator to generate electrical current while counterbalancing, with synchronized magnetic forces, periodic vibrational forces generated by piston movement; andelectrical output means for supplying an electrical current from said electrical generator to external power consuming devices.
