A propulsion efficiency improving apparatus is disclosed. The propulsion efficiency improving apparatus according to an embodiment of the present invention comprises: a pre-swirl stator which is arranged in the front of a propeller and is supported in a hull, wherein the bottom end of the pre-swirl stator is supported in a stern boss of the hull and the top end is supported in one surface of the hull located on the top of the stern boss. Therefore, the pre-swirl stator has excellent structural strength compared with a pre-swirl stator supported by a cantilever.
