The invention discloses a shape-preserving stability-enhancing propelling device for ship, which belongs to the technical field of marine side propelling equipment, the device is arranged at the bottom of a ship body, and comprises a telescopic rod, a shape-preserving plate arranged on the telescopic rod, a driving motor arranged in the shape-preserving plate and a driving propeller arranged on the driving motor, a containing cavity is formed in the bottom of the ship body, one end of the telescopic rod is connected with the bottom of the containing cavity, the other end of the telescopic rodis connected with the shape-preserving plate, and when the telescopic rod contracts to the minimum, the shape-preserving plate and the telescopic rod are completely contracted into the containing cavity, the shape-preserving plate is parallel to the longitudinal axis of the ship body, a through hole is further formed in the shape-preserving plate, the axis of the through hole is perpendicular to the longitudinal axis of the ship body, and the driving motor and the driving propeller arranged on an output shaft of the driving motor are arranged in the through hole. The shape preserving functionis achieved through contraction of the propelling device, and the effect of improving the stability of the ship body is achieved through extension of the propelling device.
