The ED0090802150-S is a zinc anode plug used as a pencil-anode style corrosion-protection part in marine engine cooling systems. Current references identify this number as a zinc anode plug and also show it cross-referenced with Lombardini 0090802150 and ZF 3311301055, which supports its use as a small threaded internal cooling-system anode rather than an external hull or drive anode.
This is a zinc anode, making it the correct material choice for saltwater use. Current dimension references for this part pattern list approximately 1/4" BSPT thread, 14 mm wrench size, 18 mm zinc length, and 10 mm zinc diameter.

Engine Compatibility
Specific Yanmar engine-family fitment is not confirmed for ED0090802150-S from the currently supported references. Fitment should be verified by part number, thread size, zinc length, zinc diameter, and the existing installed anode before ordering.
Serial Number Fitment Notice
Please verify fitment using your Yanmar engine model and serial number before ordering. Match the installed anode by part number, thread size, overall zinc length, and diameter to avoid ordering the wrong internal anode plug.
When This Part Needs Replacement
Replace this anode when the zinc is heavily consumed, pitted, shortened, or no longer able to provide sacrificial protection. Internal cooling-system anodes are easy to overlook, but they protect engine passages and cooling components that are much more expensive to repair. This zinc version is best suited to saltwater service.
Installation Notes
Install using the correct thread and sealing method for the engine application. Confirm the old anode’s thread spec, zinc length, and diameter before installation. Because this is an internal anode plug, it should be installed only where this exact plug style is already specified for the engine or cooling circuit.

Parts Desk Insight
Small pencil anodes like this protect parts customers usually never see inside the cooling system. That makes them one of the most cost-effective maintenance items on a marine engine—cheap to replace, but important if you want to avoid internal corrosion problems later.
