- Also listed for selected Honda BF25 and BF30 applications with 10-spline shafts in the manufacturer application chart, PDF page 763.
Hub and installation hardware

Before ordering
Confirm engine model and year, gearcase, shaft splines, rotation, clearance and hub hardware. Select pitch to keep the engine within its specified full-throttle RPM range. The application examples above are not a complete fitment list.
Original images represent the matching family and rotation; dimensions vary by selected part number.
