Patent ID: 8795008

Claim:
A propulsion system for a marine vehicle comprising: an electric motor having a first power transmitting element in communication with a power transmitting device whereby a first torque is transmitted to a first input of the power transmitting device; a combustion engine having a second power transmitting element in communication with the power transmitting device whereby a second torque is transmitted to a second input of the power transmitting device, wherein a transmission is arranged between the combustion engine and the power transmitting device; at least one propulsor having a power input element wherein a torque applied to the power input element generates a propulsive force to move the marine craft; the power transmitting device further comprising at least one output in communication with the at least one propulsor's power input element, and a power transmitting assembly configured such that: 1) when the first torque or the second torque is applied at any given time, there is a substantially corresponding torque of the output in communication with the at least one propulsor's power input element; and 2) when the first torque applied to the first input and the second torque applied to the second input is at substantially the same revolutions per minute, a substantially corresponding revolutions per minute of the output in communication with the at least one propulsor's power input element occurs.
