Yanmar 145410-46120 Wear Plate
The Yanmar 145410-46120 is the genuine replacement wear plate for Yanmar marine diesel sea water pumps that use this part. It is the part most often overlooked during an impeller change and the one that quietly costs the most flow.
A wear plate fails by being scored. Grit, sand and the occasional piece of shell go through the pump with the raw water, and each pass leaves a fine scratch until the face carries a set of circular grooves. Those grooves are leak paths: water carried round by the vanes slips back across the plate instead of going out of the discharge, and flow drops even though the impeller is new.

Frequently Asked Questions
Q: My pump flow dropped suddenly rather than slowly. Is the plate the cause?
A worn plate gives a gradual loss. A sudden drop usually means a sheared vane, a blocked strainer or a collapsed intake hose.
Q: How worn is too worn?
Hold the plate to the light and run a fingernail across it. Grooves you can feel, or any loss of flatness, are enough to cost flow and mean it should be replaced.
Q: Why does the plate wear at all?
Everything the strainer lets through goes between the impeller vanes and the plate. Sand and grit are abrasive, and over a season they polish a set of grooves into the face.
Q: Does it matter which way round it goes?
Yes. One face is the running face and it carries the wear pattern. Note the orientation before removing it, and fit a new plate the same way round.
