Q: Are mounting bolts included with this cover plate? A: The cover plate is supplied on its own, so reuse your existing fasteners unless they are damaged. Check the sealing surface and gasket during installation to avoid leaks.

Q: How can I confirm this fits my watercraft? A: Compare the OEM number 420811851 with your old cover plate or your machine's parts diagram. Model year and serial number can affect fit, so verify before ordering.
