Serial Number Fitment Notice

Hardware fitment depends on the exact engine model, bracket, mounting location, assembly group, and serial number range. Always confirm compatibility using the MerCruiser serial number and parts diagram before ordering, especially because the same nut can appear in multiple hardware locations.

When This Part Needs Replacement

Replace this nut if the original is missing, corroded, rounded, cross-threaded, stripped, seized, or damaged during service. It should also be replaced if the threads no longer hold proper torque or if the related bracket or mounting hardware is being renewed.

Installation Notes

Confirm the nut’s exact diagram position before installation. Match it with the correct mating stud, bolt, washer, or bracket hardware for the assembly being serviced, and tighten according to the Mercury service manual procedure for the specific engine or drive application.
