Abstract
A hybrid power device for a marine vehicle is provided that has two hybrid prime movers, an electric motor and a combustion engine, that distribute power, for example torque, to a single or dual propulsor, such as surface drives with propellers. The prime movers can apply power singly or in unison, but maintain substantially optimum propulsive efficiency in all cases. The power outputs of the prime movers are in communication with a power transmitting device such as a gear box that may combine the power outputs to drive a single propulsor, or may have a power-splitting embodiment driving dual propulsors. In addition, multiple hybrid power devices may be deployed in other embodiments.
