Yanmar 124223-42080 Seal for 2GM20F and 3GMF

The Yanmar 124223-42080 is the genuine replacement seal for the sea water pump fitted to 2GM20F and 3GMF Series engines. It is a small part that decides whether the pump has a long life or a short one.

These pumps are usually fitted with more than one seal separating the water side from the bearing side. Replace them as a set when the pump is apart - they have the same age and the same hours, and reaching them is most of the work.

Frequently Asked Questions

Q: How often should seals be replaced?
Whenever the pump is apart far enough to reach them, and immediately if there is any sign of water tracking past them.

Q: There is salt crusting under the pump. Is the seal gone?
That is the classic sign. Water is passing the seal and evaporating on the outside. Deal with it early, because the next thing it reaches is the bearing.

Q: Can I fit a new seal to a worn shaft?
Not with much hope. A groove where the old lip ran gives the new one nothing flat to follow, and it will weep again quickly.

Q: Which way round does the seal go?
Lip toward the water it is sealing, so pressure pushes the lip against the shaft rather than away from it. Note the orientation of the old one before it comes out.
