Yanmar 124223-42110 Gasket for 2GM20F and 3GMF

The Yanmar 124223-42110 is the genuine replacement gasket for the sea water pump fitted to 2GM20F and 3GMF Series engines. It goes between two machined faces and keeps what is behind them where it belongs.

Fit it the right way round. The holes match the port pattern of that joint and are often not symmetrical, so a gasket fitted reversed can block a passage entirely and leave you with a pump that turns and delivers nothing.

Frequently Asked Questions

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.

Q: Should I use sealant as well?
No. The joint is designed to seal on the gasket alone, and sealant squeezed into a water passage creates a fault that is very hard to find later.
