Volvo Penta D2 55A Water pump shim

[MagicalArmchair]

On a routine swap of impeller on my winter service, I noticed a shim, or plate behind the impeller.

Is this normal for a D2 55 water pump?

I notice D2-55 mentioned here. Has that got anything to do with it?

It's the "wear plate" ( NLA as a separate part from VP )
