ABSTRACT:
An outboard propulsion system is disclosed. In some embodiments, the outboard propulsion system includes a generator operable to produce a first electrical signal, an engine electrically coupled to the generator, an inverter electrically coupled with the generator to receive the first electrical signal, wherein the inverter is adapted to transform the first electrical signal into a second electrical signal, all electric motor electrically coupled to the inverter to receive the second electric signal, a shaft mechanically coupled to the electric motor and rotatable by the electric motor when the electric motor receives the second signal, and a thrust generation device mechanically coupled to the shaft. The engine is configured to operate the generator. The thrust generation device is adapted to rotate when the shaft rotates.
