The best method is to consult your engine's service manual or parts catalog to confirm the OEM part number is 27-49955 or 8M0077608.

You may notice an oily film on the engine pan or lower unit, or spots of oil on the ground where the engine is stored. Replacing the gasket during your regular fluid changes is the best way to prevent this.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs this gasket reusable?\u003c\/summary\u003e\u003cp\u003eNo, drain plug gaskets are designed as single-use crush washers. Once torqued, they deform to create a seal. Reusing an old gasket significantly increases the risk of leaks.
