The invention provides a guide pipe of a propeller and a manufacturing method, and belongs to the field of ship propellers. The manufacturing method comprises the following steps: providing an outer ring frame, providing a hub body, providing a plurality of guide vanes, placing the plurality of guide vanes between the outer ring frame and the hub body, and enabling a third positioning structure of each guide vane to be mutually clamped with a corresponding first positioning structure of the guide vane, the fourth positioning structure is clamped with the second positioning structure corresponding to the guide vane, the third assembly hole is coaxial with the first assembly hole corresponding to the guide vane, and the fourth assembly hole is coaxial with the second assembly hole corresponding to the guide vane; and connecting pieces are inserted into the first assembly hole and the third assembly hole which are coaxially arranged, and the second assembly hole and the fourth assembly hole which are coaxially arranged, so that the guide pipe is obtained. The machining precision of the guide pipe can be improved.
