Disclosed is a ship propulsion system having a counter rotating propeller. The ship propulsion system comprises: a bevel gear; a first hub having at least one first propeller attached to an outer circumferential surface thereof, and a first inclined thread engaged with the bevel gear formed at one side thereof; and a second hub having at least one second propeller attached to an outer circumferential surface thereof, receiving grooves for receiving the bevel gears continuously formed on an inner circumferential surface, and a second inclined thread formed on one side opposing to the first inclined thread and meshing with the bevel gears by interposing between the bevel gears. The present invention intends to provide a ship propulsion system having a counter rotating propeller capable of solving alignment problem between propellers as well as securing economic feasibility and ease of use.
