Genuine OEM Mercury / Quicksilver Engine Oil Drain Plug Seal (Part # 8M0188614)

Prevent crankcase oil leaks and maintain proper oil pressure with the Genuine OEM Mercury / Quicksilver Engine Oil Drain Plug Seal (Part # 8M0188614). Designed specifically for engine oil sump drain plugs on select Mercury 4-stroke outboards, this factory-engineered seal gasket forms a tight, leak-proof crush barrier between the drain screw flange and the oil pan.

Engine oil drain gaskets compress upon installation to create a watertight and oil-tight seal. Reusing an old, flattened, or hardened gasket can lead to slow oil leaks into the water or engine pan. Replacing this single-use washer during every 100-hour or annual oil change is essential preventive maintenance for keeping your engine oil contained and your outboard running smoothly.
