Mercury MerCruiser Quicksilver 87560091 is a genuine OEM thrust bearing race identified in current Mercury parts references as BEARING Thrust (.091) (RED). Current MerCruiser parts diagrams place this red-coded .091 race in the upper gears and components and driveshaft housing / drive gears sections of Bravo and Blackhawk stern drive assemblies, where thickness-specific bearing races are used during gear-set setup and service.

Engine Compatibility
The strongest supportable fitment for 87560091 is MerCruiser Bravo One, Bravo Two, Bravo Three, and Blackhawk drive / transom assemblies, specifically in upper gears and components and driveshaft housing and drive gears applications. Current parts references show it in both gasoline and diesel Bravo stern drive parts coverage, as well as Blackhawk 1994–1995 assemblies.
Serial Number Fitment Notice
Verify fitment by exact MerCruiser drive model, serial number, and the correct bearing-race thickness specification before ordering. With 87560091, the important check is not just the drive family but the exact .091 red thickness requirement, because current Mercury parts references also show nearby alternatives in .094 light blue and .097 green for the same service area.
When This Part Needs Replacement
This part is typically replaced during upper gear or driveshaft housing service when gear setup calls for a different race thickness, or when the existing thrust race shows wear, damage, or should be renewed during teardown and reassembly. That guidance is a practical service inference based on its documented placement in upper gear and driveshaft housing assemblies as a thickness-specific thrust race.
Installation Notes
Install 87560091 only after confirming the exact Mercury parts diagram and thickness requirement for the drive being serviced. Current diagrams show it alongside related thrust bearing parts such as 31-86771 thrust bearing, 31-86768A2 thrust bearing with race, 23-86770 collar, and the upper driveshaft and gear-set components, so setup order and race selection should be checked carefully during service.
Alternate/Superseded Part Numbers
Current sources reviewed show 87560091 as the active OEM number. Related thickness variants used in the same service position include 87560094 for .094 light blue and 87560097 for .097 green.
Parts Desk Insight
This is one of those parts that is easy to misorder because the drive family can be correct while the thickness is wrong. Matching 87560091 by the exact .091 red spec is the better move than ordering by the generic thrust-race description alone.
