About This Part
Genuine Mercury / Quicksilver 11-22024 is an OEM 7/16”-14 hex nut used across a variety of Mercury Marine engine and accessory assemblies. Mercury parts references show it in seawater-pump mounting, thermostat and cooling-system hardware, transmission-related assemblies, and other engine bracket locations across several MerCruiser engine families. Because 22024 is a shared hardware number rather than a component-specific fastener, compatibility and torque specification must be confirmed from the parts diagram and service manual for the exact assembly being serviced — not inferred from thread size alone.
Compatible Applications
- MerCruiser 470 / 470 MIE 3.7L — engine and accessory hardware
- MerCruiser 5.0L / 5.7L / 6.2L / 7.4L / 8.1L / 8.2L GM V8 families — bracket and accessory mounting
- MerCruiser Black Scorpion / MAG / Horizon / MIE variants — hardware positions by serial number
- MerCruiser Bravo sterndrive assemblies — hardware positions by serial number
- Cummins MerCruiser Diesel applications — hardware positions by serial number
- Seawater pump mounting assemblies — used with stud 806591 and lockwasher 32993 in applicable diagrams
- Thermostat and cooling-system hardware positions
Confirm compatibility by exact engine model, serial number, and parts-diagram position. The same nut appears in multiple assembly locations across different engine families.
When to Replace
Replace this nut if it shows any of the following:
- Damaged, stripped, or cross-threaded engagement
- Severe corrosion or surface pitting
- Rounded hex flats from incorrect tool use
- Distortion from overtightening
- Seized threads that prevent proper removal or installation
- The service procedure specifies replacement hardware rather than reuse
Installation Notes
Confirm the nut’s exact diagram position before installation and inspect the mating stud or bolt threads and any associated lockwasher or flat washer. For seawater-pump mounting applications, Mercury diagrams show 22024 used together with stud 806591 and lockwasher 32993 — inspect all three components when servicing this location. Torque to the specification in the Mercury service manual for the exact assembly being serviced — do not apply a generic torque value based on thread size alone.
Cross-Reference Part Numbers
- OEM: 22024 / 11-22024
- GTIN: 745061130654
- Thread: 7/16”-14
- Used with (seawater pump applications): Stud 806591, lockwasher 32993
- Note: No confirmed Mercury OEM superseding number identified.
Parts Desk Insight
22024 is a shared Mercury hardware nut that appears across many different assemblies — its strongest documented applications are seawater-pump and engine-bracket mounting, but it also appears in cooling, transmission, and other hardware positions. The most common mistake is ordering by thread size alone rather than matching the OEM part number to the exact diagram position. When servicing seawater-pump mounting hardware, the complete hardware stack — stud 806591, lockwasher 32993, and nut 22024 — should be inspected together, as corrosion often affects all three components in a saltwater environment.
