Mercury MerCruiser Quicksilver 11-814101 is a .250-20 stainless steel nut used across select Mercury, Mariner, and MerCruiser assemblies. Current Mercury parts references show 11-814101 / 814101 superseding to the current functional replacement 8M0207776, and note that the replacement may look different from the original while serving the same function.

Engine Compatibility
This nut is not limited to one engine family. Mercury parts references show it across a wide range of select Mercury, Mariner, and MerCruiser applications, including outboard powerhead and jet-drive assemblies, MerCruiser engine assemblies, performance drive applications, steering systems, remote controls, instruments, gauges, and related component groups depending on the exact diagram location.
Serial Number Fitment Notice
Hardware fitment depends on the exact engine, drive, control assembly, bracket, component group, and serial number range. Always confirm compatibility using the Mercury or MerCruiser serial number and parts diagram before ordering, especially where older 11-814101 has been replaced by 8M0207776.
When This Part Needs Replacement
Replace this nut if the original is missing, corroded, rounded, cross-threaded, stripped, seized, or damaged during service. Stainless hardware should also be replaced when the threads no longer hold proper torque or when the nut has been removed from a critical assembly where secure fastening matters.
Installation Notes
Confirm the nut’s exact position in the Mercury parts diagram before installation. Match it with the correct mating screw, stud, washer, or bracket for the assembly being serviced, and tighten according to the Mercury service manual for the specific application. Do not substitute generic hardware unless the thread, material, locking style, and application requirements are confirmed.

Parts Desk Insight
This is a small hardware item, but the application range is broad. The safest way to match it is by the exact parts diagram location, not by engine size alone, because the same .250-20 stainless nut appears in several different Mercury and MerCruiser assemblies.
