This propeller cone is used for mounting on Volvo Penta DuoProp drives (including DP280, 290, and DP-A to G) and is suitable for A and B series propellers. This is a high-quality aftermarket replacement for OEM No. 872614 (16mm) or 872549 (20mm).
Choose the 16mm variant if your locking bolt has an M8 thread (8mm thick, 13mm socket). Choose the 20mm variant if you use an M12 locking bolt (12mm thick, 19mm socket). Note: This is the cone only; you must reuse the locking bolt and washers from your current set for installation.
