Mercury / MerCruiser Quicksilver #10-32 Throttle Cable Nut 8267086
Part Number: 8267086 | Service Format: 11-8267086 | Thread: #10-32 (UNF) | Supersedes: 20190 | GTIN: 745061521025
Genuine Mercury / MerCruiser OEM #10-32 nut used across several Mercury Marine throttle, carburetor-linkage, and electrical assemblies. Its strongest documented MerCruiser application is as the retaining nut for the throttle-cable-to-carburetor / throttle-lever screw, working together with the corresponding washer and cable hardware. Mercury's current OEM number is 8267086 (service format 11-8267086), replacing the earlier 20190. Because this is a shared hardware number that also appears in selected auto-trim and older ignition/switch-box assemblies, always confirm the diagram position for your specific engine before ordering.

Compatible Applications
Fitment must be confirmed against the Mercury parts diagram for your specific engine model and serial number. Mercury uses several #10-series nuts in adjacent assemblies — confirm 11-8267086 specifically in the diagram.
- MerCruiser 3.0L (GM 181 L4) — carburetor throttle-cable / throttle-lever retaining nut
- MerCruiser 5.7L (GM 350 V8) — carburetor throttle-cable / throttle-lever retaining nut
- MerCruiser remote-control cable to throttle-lever connections (selected applications)
- Selected MerCruiser automatic-trim screw hardware
- Selected older Mercury outboard ignition / switch-box assemblies (verify by diagram)
Diagram Position
- Throttle-cable-to-carburetor / throttle-lever screw — retaining nut position
- Commonly paired with throttle-cable washer 847883 and washer 8M0204666 in applicable MerCruiser carburetor assemblies
- One nut per throttle-cable connection on documented MerCruiser carb assemblies
When to Replace
- Threads are stripped, damaged, or will not engage cleanly on the mating screw
- Hex flats are rounded and can no longer be turned with a wrench
- Nut is severely corroded or distorted from overtightening
- Nut goes missing during throttle-cable, carburetor, or linkage service
Installation Notes
- Inspect the mating screw, stud, washer, bushing, and throttle-linkage components before installing the new nut
- Tighten to the torque specification in the Mercury service manual for the exact assembly — do not use a generic fastener torque
- Clean threads on both the nut and mating screw before installation
- Replace companion washers if they show any distortion or corrosion while the assembly is apart

Parts Desk Insights
Best use case: 8267086 is the go-to throttle-cable retaining nut for carbureted MerCruiser 3.0L and 5.7L service. Any time the throttle cable is disconnected or the carburetor is pulled, this nut should be inspected and replaced if there is any doubt — it is an inexpensive part that keeps the throttle connection secure under constant engine vibration.
Common customer issue: Ordering the older number 20190 or substituting a generic #10-32 nut from a hardware store. Mercury's current OEM number is 8267086 — if you search for 20190, you should be receiving 8267086 as the current replacement. A hardware-store nut may look identical but can differ in plating, thread class, and load specification. For a throttle-cable connection cycling continuously under load, the OEM spec matters. Always match the part number in your diagram before ordering.
