How to Match This Part

This aftermarket exhaust mixing elbow replaces Yanmar Marine reference 128890-13530. It mixes raw cooling water into the exhaust stream and routes the mixture away from compatible Yanmar YM-series marine diesels.

Match this part in this order:
1. Original part number on the elbow or parts list (128890-13530 or superseded 128397-13530)
2. Engine model on the engine identification plate
3. Physical form and hose sizes against the product images and your existing hoses

Confirm a square 4-bolt flange, a straight main tube with a vertical water-injection port near the flange, an 11/16" (17 mm) water inlet, and a 2" (50 mm) exhaust outlet before ordering. See the product images for flange orientation and port location.

Part Number Cross-Reference

Some YM engines changed mixing-elbow hose size by serial range. Verify your water-injection hose ID matches the 11/16" (17 mm) inlet on this unit before purchase.

Installation Guide

1

Allow the engine to cool completely and disconnect the battery before starting work.

2

Compare the new elbow to the original for square 4-bolt flange layout, vertical water-port location, and hose diameters before removing the old part.

3

Remove the old elbow, clean the manifold mating face, and install a suitable exhaust gasket and fasteners as specified in the engine service manual (gasket commonly referenced as Yanmar 128370-13201 or equivalent).

4

Seat the new elbow on the flange, tighten fasteners evenly to the manufacturer’s torque values, then reconnect the water inlet hose and 2" exhaust hose with secure clamps.

5

Reconnect the battery, start the engine, and check for water or exhaust leaks at the flange and hose joints before returning the vessel to service.

Note: Follow the Yanmar service manual for torque and gasket requirements. Professional installation is recommended.

Troubleshooting & FAQ

Is this an OEM or aftermarket part? +

This is an aftermarket replacement manufactured for the Yanmar 128890-13530 application. It is not a genuine Yanmar OEM part.

Does a gasket come with this elbow? +

Do not assume a mounting gasket is included. Plan to use the gasket called out in your engine parts list (commonly Yanmar 128370-13201 or equivalent) unless your order confirmation states otherwise.

My water hose looks larger than 11/16"—will this fit? +

This listing is built around an 11/16" (17 mm) water inlet. If your engine uses a larger injection hose (often about 22 mm on some later YM installations), do not force-fit this elbow—confirm hose ID and OEM number first.

Is my 3GM30 or 3GM30F covered? +

Only the engine models in the compatibility table above are confirmed for this listing. GM-series engines often use a different mixing-elbow reference. Match the original OEM number, flange layout, and water-inlet size before purchasing.

Important Notes

  • A wrong water-inlet size can leak, overheat, or allow seawater into the exhaust path—always verify hose ID and OEM number.
  • This unit uses a square 4-bolt flange and a straight-tube form; do not confuse it with triangular 3-bolt Yanmar elbows used on other series.
