Mercury Engine Oil Drain Plug Seal (135HP-400HP FourStroke & Verado) 8M0188614 (* SS# 888593) is a genuine OEM replacement drain plug gasket designed to create a reliable seal during engine oil changes. Replacing the drain plug seal each time the oil is serviced helps prevent leaks and ensures proper sealing of the engine oil drain plug.

• Mercury 135HP-400HP FourStroke outboards
• Mercury Verado 135HP-300HP L6 outboards

This genuine Mercury seal is manufactured to the original specifications for proper fit, sealing performance, and long service life. A fresh drain plug gasket helps maintain the integrity of the lubrication system by preventing oil seepage around the drain plug after routine maintenance.

Drain plug seals are inexpensive but essential service items that should be inspected and replaced whenever they become worn, compressed, or damaged. Using a genuine Mercury replacement helps ensure a proper seal and reduces the risk of oil leaks caused by reusing an old gasket.
