The latest, strongest rudder gudgeon design with welded sleeve bushings provides large, smooth bearing surfaces between rudder pins and gudgeons. Replace flared gudgeons with their sharp edges and point loading that can cause early rudder pin failure. For Hobie® 14, 16 and 17, order separate upper and lower gudgeons. For all other Hobie® cats with new-style castings, post 1986, order 4 for a complete set . Replacement for Hobie part #50101401.
