Parts Desk Insights

Best use case: This is the right part when you have confirmed 19686 on the parts diagram for your specific assembly and need to replace a damaged or corroded bracket to restore correct component alignment. Because this part is discontinued, it’s worth ordering while stock is available if your service schedule calls for it.

Common issue: Ordering a bracket by appearance or general description rather than by the diagram part number. Bracket designs across MerCruiser production years can look very similar but differ in hole spacing, mounting geometry, and material thickness. The part number on the diagram is the only reliable way to confirm the correct bracket for your assembly.
