Serial Number Fitment Notice
Confirm fitment using your Yanmar engine model, serial number, and exhaust mixing elbow parts diagram before ordering. Exhaust elbow components can vary by engine version, cooling configuration, and production range.
When This Part Needs Replacement
Replace this joint if the threads are corroded, seized, cracked, leaking, heavily scaled, or damaged during exhaust elbow removal. It should also be inspected whenever the mixing elbow assembly is serviced.
Installation Notes
Inspect both mating elbow sections before installation. Clean the threads, check for corrosion or cracking, and use the sealing method specified in the Yanmar service procedure. Avoid forcing corroded exhaust fittings, as surrounding elbow components may also need replacement.

Parts Desk Insight
This part lives in a harsh exhaust/water mixing environment, so corrosion is common. When replacing the joint, it is smart to inspect the full mixing elbow assembly at the same time instead of treating the connector as an isolated failure.
