Description

Mercury 89238 is a genuine OEM oil seal used in select Mercury marine applications. The clearest matching references identify it specifically as a driveshaft oil seal, while another application reference places it in water pump service on certain Mercury outboards. That makes this a model-specific sealing part that should be matched by exact application, not by size or appearance alone.

Key Features

• Genuine Mercury / Quicksilver part number 89238
• Commonly listed as Oil Seal
• Frequently identified as a driveshaft oil seal

Engine Compatibility
Available fitment references tie 89238 to select Mercury outboards, with one source specifically connecting it to 100HP–165HP applications in water pump service. Because seal placement can vary by engine family and lower-unit setup, fitment should still be confirmed by the exact engine model and serial number before ordering.

Serial Number Fitment Notice
Please confirm fitment by engine model and serial number before ordering. This is especially important for oil seals, where the correct part depends on the exact shaft, housing, and service location.

When This Part Needs Replacement
Replace this seal whenever the original seal is leaking, cut, hardened, worn, or no longer sealing correctly. It is also a smart replacement item during lower-unit or water-pump service when the original seal is already disturbed or showing age. This guidance follows the part’s function as an oil seal.

Installation Notes
Install only on the correct Mercury application and verify the removed seal against the part number, model, serial number, and service location before ordering. Matching the original seal exactly is the safest approach.
