You bought them a year ago, handled them, installed them and now you are pondering if you got screwed because of surface oxidation making a few casting imperfections visible? Even in the top pic of post#2 shows some scaling that is oxidized in your post#3 on the flange...(BTW - I have seen props look like that after cleaning with acid over the years and the boat was land locked Fresh water)

What drew you attention to the props being considered NFG at this point? Did the hub burn through or

When buying a product that is less than 50% of new you have to define what the sellers definition of "good" condition is versus what you expect. If you want new condition than find a used set for sale that is no doubt in that condition or do yourself a favor and buy new. To answer your question bluntly you got what you paid for.

Ive never seen a prop fail , from some pitting in the webs. That is the most
difficult part on a prop to cast. Run the **** out of them .
To late to complain , its on you.

Thanks for the feedback guys. The pitting is pretty significant on 2 of the hubs and less so on the third. if I can find another prop I’m probably gonna swap this one out. It looks more significant than surface corrosion to me. I can almost stick a screw driver in them.

You'll throw a blade on them, especially if they have ever been lab finished, well before you'd ever have a webbing failure. As others have stated, that is not corrosion.

Concur as casting surface gas defect in the nickel based material which is not uncommon. Manufacturers usually have a pass/fail criteria (depth, length, width, etc..) addressing visual surface or NDE detected defects based on engineering data or industry standards.

Like stated above, the possibility of having a blade failure is greater than the web giving away.

Run them before assuming they are paperweights.
