About This Part
Genuine Mercury / Quicksilver 12-24664 is an OEM flat washer used in MerCruiser engine and sterndrive assemblies. It is built to exact factory tolerances to ensure correct load distribution, prevent fastener pull-through, and protect mating surfaces in marine applications. The pack of 5 is a sales quantity — confirm the number required for your specific assembly from the parts diagram before ordering, as washer requirements vary by application.
Compatible Applications
- MerCruiser engine and sterndrive assemblies specifying washer 24664 or 12-24664 in the parts diagram
Always confirm fitment by engine model, serial number, and the exact parts-diagram position. Washer dimensions and applications vary across Mercury and MerCruiser assemblies — do not substitute by appearance or diameter alone.
When to Replace
Replace this washer if it shows any of the following:
- Corrosion or surface pitting affecting the bearing surface
- Bending or distortion from overtightening
- Deep scoring or wear around the center hole
- Damage during disassembly
- Missing from a factory hardware stack
Installation Notes
Install in the exact position and quantity shown in the Mercury parts diagram for the assembly being serviced. Clean mating surfaces before installation and torque the associated fastener to the Mercury service manual specification for the specific assembly — do not apply a generic torque value based on washer size.

Parts Desk Insight
24664 is a shared Mercury flat washer used across engine and sterndrive assemblies, and the most common issue is simply not having enough on hand when servicing a full assembly. Washers in marine environments corrode and distort over time, and replacing the full hardware stack rather than reusing old washers is the better practice on any thorough service. The pack of 5 covers most single-assembly requirements and provides a couple of spares for the toolbox.
