SIERRA OMC Sterndrive 2.000 in. Yoke Seal – 18-2067

Description

SIERRA OMC Sterndrive 2.000 in. Yoke Seal – 18-2067

A dimensional replacement rotary shaft/oil seal for the specified marine gearcase, sterndrive or engine assembly. Correct seal size and lip orientation are critical to retaining lubricant and excluding water.

• Application: Selected OMC sterndrive yoke/drive assemblies using OEM seal 911685.
• Dimensional marine replacement seal; match shaft and bore dimensions before installation.
• Replace damaged, hardened or leaking seals during gearcase/drive service rather than reusing old seals.
• Lubricate the seal lip as specified and install squarely without damaging the sealing edge.
• Confirm the OEM interchange and shaft location because visually similar Sierra seals may use different diameters or lip designs.

This is an application-specific marine service part. Confirm the engine or sterndrive model, serial range and OEM reference before installation.

Application: Selected OMC sterndrive yoke/drive assemblies using OEM seal 911685.
