Application and hardware
For cataloged 25 HP CT, 30 HP FourStroke (2005 and earlier), and 40–60 HP two-stroke and FourStroke standard-gearcase applications. Match model, year and shaft before ordering.
Match the exact engine model, year, gearcase, shaft splines and rotation. A horsepower range is not universal fitment. Use the correct thrust washer, adapter and retaining hardware specified for your engine and hub.
