There is disclosed a hybrid propulsion system for a marine vessel, comprising in sequence a propulsion combustion engine (1), an electromotor (6) a following transmission unit (12) and an exit shaft (13) for a drive purpose, and where said electromotor (6) is connected to a chargeable accumulator unit (7), the described propulsion system comprises a shaft (5), which between the propulsion combustion engine (1) and the electromotor (6) and between the electromotor (6) and a transmission unit (12), is divided in several shaft parts (5B,5D) interconnected via one or more joint units (4), and that it is able to absorb vibrations, and individual axial and transverse movements of the individual shaft parts (5B-5D) in the main shaft (5). The hybrid propulsion system is characterized in that the exit shaft part (5A) from the propulsion combustion engine (1), passes through a clutch unit (3) operating in a ratio of approximately 1:1, there are at least one rotatable elastic joint units (4) interconnected to the shaft parts (5B,5D) between said propulsion combustion engine (1) and electromotor (6) and the electromotor and the transmission (12) respectively; and where each of said at least one elastic joint unit (4) comprises universal mutually opposite joint flange structures which are mutually connected by a number of pivotable link arms (20) each extending from a first flange structure (41) to the other flange structure (51) and is anchored in a pivotable manner to said respective flange structures to absorb vibrations in the hybrid propulsion system. A method and uses of the invention are also disclosed.
