The present invention provides a ship outboard propeller hub assembly, which comprises: a shaft coupling port which is inserted and coupled to the outer side of the shaft of an engine, has a plurality of shaft coupling grooves which are spaced apart from each other along the circumferential direction on the inner circumferential surface thereof while being extended in the same direction as the longitudinal direction of the shaft, and has a plurality of first coupling protrusions extended in the same direction as the longitudinal direction of the shaft while being spaced apart from each other in the circumferential direction on the outer circumferential surface thereof; a buffering hub which is inserted and coupled to the outer side of the shaft coupling port, has a plurality of first coupling grooves coupled to the first coupling protrusions on the inner circumferential surface thereof, has a plurality of second coupling protrusions extended in the same direction as the longitudinal direction of the shaft while being spaced apart from each other in the circumferential direction on the outer circumferential surface thereof, and has elastic restoring force; and a hub coupling port which is inserted and coupled to the outside of the buffering hub and has a plurality of second coupling grooves coupled to the second coupling protrusions on the inner circumferential surface thereof.
