Sierra 18-2155 Shift Shaft Housing Bushing, Replaces Mallory 9-76134, Aluminum

The Sierra 18-2155 Shift Shaft Housing Bushing is an aluminum bushing used in Mercury outboard propeller shaft assemblies. It is a knob-type hardware component that fits into the shift shaft housing, providing a wear surface for shaft engagement. The bushing is machined from aluminum for durability and resistance to corrosion in a marine environment, and it is finished with a painted white coating for a clean, modern appearance that matches surrounding outboard hardware.

Each unit ships as a single Shift Shaft Housing Bushing, sized as a direct fit for applications calling for Sierra part number 18-2155 or its cross-referenced equivalent. Because shift shaft components see repeated mechanical engagement every time the outboard is shifted, the bushing is a wear item worth keeping on hand for routine maintenance or shift-linkage repair.
