Yanmar 23414-080012 Gasket
The Yanmar 23414-080012 is the factory gasket used in Yanmar marine diesel sea water pumps that use this part. It costs very little and it is the part whose failure is hardest to diagnose, which makes it one worth renewing rather than reusing.
A gasket takes a set in the joint and usually sticks to one face, so it almost always tears on disassembly. Replacing rather than reusing is not a preference, it is the practical reality of opening the joint. Clean both faces back to bare metal with a plastic scraper before the new one goes on, and check for scoring across the joint while you are there.

Frequently Asked Questions
Q: Why is a small weep worth chasing?
Because sea water trapped between two faces pits them, and a pitted joint will not seal properly again even with a new gasket.
Q: Is a mounting gasket different from a port gasket?
They seal different joints and are cut differently. Both should be renewed whenever their joint is disturbed.
Q: Can I reuse a gasket that came off in one piece?
It has taken a set in the joint and lost the compression it needs to seal. On a salt water joint that is how corrosion starts between the faces.
Q: Does it matter which way round it goes?
Yes. The holes match the port pattern and are often not symmetrical, so a gasket fitted reversed can block a water passage.
