Can SS props be cupped or re-pitched?

I have a 9.25"X12P stainless prop for my 25HP Johnson (1975).

It is a nice prop but it lugs the engine about 200rpm below recommended WOT rpm on my inflatable.
I would like to get an inch of pitch taken out. Can they do that with SS props?
I ask because the only other SS ever made for this motor was a 9P and that's way low
I have a 10P aluminum and it overrevs with that... I need 11P

any idea on the cost if so?

If a prop is cupped, should the pitch be adjusted? (up or down)

Yes a good prop shop can modify a ss prop they may suggest removing some cup or changing pitch.I've seen some surprising results removing cup.As I understand it they can move the cup around as well.

A prop shop can do almost anything, except increase the size.
