Key Features
- Genuine Mercury / Quicksilver part number 8M0188614
- Identified as a seal, commonly described as an oil drain seal / gasket / washer
- Used as a sealing component for the engine oil drain connection
- Best matched by exact part number, engine model, and serial number
Engine Compatibility
The strongest fitment trail connects 8M0188614 to Mercury Verado outboards. Multiple sources specifically tie it to L6 Verado applications, while another product reference identifies it for 150–200 HP L4 Verado outboards. Because drain-seal usage can vary by engine family and service-point design, 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-service seals, where the correct part depends on the exact drain plug and engine configuration.
When This Part Needs Replacement
Replace this seal whenever the oil drain plug is removed during service, or when the existing seal is flattened, cut, hardened, leaking, or no longer sealing correctly. This guidance follows the part’s role as an oil drain sealing washer/gasket.
Installation Notes
Install on the correct Mercury oil drain plug application and verify the old seal against the part number, engine model, and serial number before ordering. A fresh seal helps maintain a proper leak-free oil drain service.
