The invention discloses a propulsion device for a ship. The propulsion device has a first direction and a second direction which are perpendicular to each other. The first propeller group and the second propeller group are arranged at the incident flow end of the main body in a spaced mode in the first direction, and the main body is provided with a main axis parallel to the first direction. Wherein the first propeller group comprises a plurality of first propellers, the plurality of first propellers are uniformly arranged in an array manner around the circumferential direction of the main axis, the second propeller group comprises a plurality of second propellers, and the plurality of second propellers are uniformly arranged in an array manner around the circumferential direction of the main axis; the first propeller and the second propeller are arranged at intervals in the second direction. The first propeller is located on the side, close to the main axis, of the second propeller. The driving mechanism, the first transmission mechanism and the second transmission mechanism are arranged on the main body and used for driving the first propeller and the second propeller to rotate. According to the technical scheme, the technical problem that an existing propelling device is low in propelling efficiency can be solved.
