Disclosed is a propulsion system for a ship provided with a double inversion propeller. The propulsion system for a ship comprises: a first hub fixedly coupled to a drive shaft providing rotation force and allowing a first blade to be attached onto an outer circumferential surface thereof; a second hub allowing at least one second blade to be attached onto an outer circumferential surface thereof and having an inner side gear on a circumferential surface of the drive shaft and an outer side gear which are formed in a concentric shape at one side thereof; and a planetary gear structure including a plurality of planetary gears interposed to be engaged to the inner side gear and the outer side gear, respectively. According to an embodiment of the present invention, idle of the planetary gear transferring rotation force of the drive shaft to the outer side gear is interrupted so that torque of the drive shaft can be maximally transferred to the outer side gear.
