Genuine Mercury O-Ring — 4.109" x .139" Cross-Section
This is the genuine OEM O-ring used throughout Mercury MerCruiser and Quicksilver engine and drive assemblies wherever a 4.109" ID x .139" cross-section seal is specified. Manufactured to factory tolerances, it restores a leak-free seal during resealing work, overhaul, or any service that disturbs the original seating surface.

Fitment
Match this part to your Mercury parts diagram using your engine model, serial number, and assembly location. Similar seals across Mercury product lines can vary by production range — always confirm the part number before ordering.
When to Replace
Replace during any disassembly, resealing, or overhaul where the existing O-ring shows signs of crushing, hardening, tearing, flattening, or contamination — or any time the seating surface is disturbed.
Installation
Clean mating surfaces thoroughly before installation. Replace any related seals or gaskets disturbed during disassembly. Follow the Mercury service manual for correct orientation, lubrication, and torque specifications.
Parts Desk Insights
Best use case: This O-ring is most commonly needed during water pump housing service, thermostat housing reseals, and drive unit overhauls on MerCruiser stern drives and inboard engines. Always order by the diagram part number first — this is especially important on repowered boats or assemblies that may have been updated under a superseded number. If your diagram shows 32068 or 25-32068, this is the correct part.
