What if you had a SS prop on a SS shaft with SS thru holes/sea cocks.

Same grade on the galvanic scale and no deterioation, or all the metal slowly but surely goes to he!!..? (Still need zinks?)

Yes, Galvanic Table correlation. However even if your castings were poured with the same pot molten, you would have different content in the same classification of materials. Mainly the reason they are Alloys! Pure for Pure for Mass comes into effect. But yes still exchanging and loosing. Check the Mercathode thru hull system. You could install this and not have to worry about much other than a small source of power

Galvanic Table/Classification
But I was trying to simplify on a basic basis.
