Yamaha OEM Oil Drain Plugs & Gaskets

Genuine Yamaha engine drain plug gaskets and lower unit plug gaskets. A drain plug gasket is made to seal once, and a reused one is a common cause of a slow oil leak after a service. The lower unit has its own gaskets on the drain and vent plugs, and those keep water out of the gearcase.

Frequently asked questions

Can I reuse a drain plug gasket?

No. Fit a new one every time the plug comes out.

Do the lower unit plugs need new gaskets?

Yes, both of them, at every gear oil change.

Which gasket fits my Yamaha?

It varies by engine family. Look up your model in the Yamaha parts diagrams or send us the model and serial number.

Are they included in the kits?

Yamaha oil change kits include the drain plug washer. Buy gaskets here if you service with Yamalube bought separately.
