## 🛠️ Service Notes

-   This is a steering component, so treat wear as safety-related and do not return the boat to service on a gear with chipped teeth
-   The published serial reference is only partly given, so confirm against the unit serial before ordering
-   Renew the meshing gear if its flanks are marked, as a new gear against a worn one wears fast
