SIERRA Mercury / MerCruiser 0.750 in. Shaft Oil Seal – 18-2011

Description

SIERRA Mercury / MerCruiser 0.750 in. Shaft Oil Seal – 18-2011

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 Mercury and MerCruiser gearcase/drive applications using the listed 26-series OEM seals.
• 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 Mercury and MerCruiser gearcase/drive applications using the listed 26-series OEM seals.
