Disclosed are an apparatus for improving propulsion efficiency, and an installation method thereof. The apparatus for improving propulsion efficiency comprises: a pre-swirl stator coupled with a stern boss; and an inserted protrusion unit protruding from the stern boss and inserted into a root unit of the pre-swirl stator when the pre-swirl stator is coupled with the stern boss. The apparatus for improving propulsion efficiency can easily dispose the pre-swirl stator, increase a coupling strength between the pre-swirl stator and the stern boss, reduce shaking of the pre-swirl stator coupled with the stern boss, reduce work processes and work hours, and easily perform welding.
