Yanmar 129150-01881 Mounting Gasket

The Yanmar 129150-01881 is the factory mounting 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.

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: 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.

Q: How should the faces be prepared?
Clean both back to bare metal with a plastic scraper and check for scoring across the joint. Avoid abrasive discs, which dish the face and create the leak you were trying to cure.

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.
