Mercury MerCruiser Drain Screw Washer Seal – New Yellow – OEM 26-830749

Small part, big importance.

This is the official Mercury/MerCruiser drain screw washer seal, part number 26-830749.

It's that little yellow washer that goes on your lower unit or outboard drain screw.

If yours is crushed, dried out, or leaking, swap it out before you hit the water.

It's a brand new OEM-type seal.

Cheap insurance against water intrusion and gear oil leaks.

Fits a bunch of Mercury and MerCruiser applications.

Just pull the old one off, slide this on, and torque it down.

Don't risk a ruined gearcase over a fifty-cent part.

Get a few spares while you're at it.
