I have a mirage 14 5/8 X 23. Its nearly impossible to find a mirage PLUS in this pitch and diameter without spending $700 on a new one.
My understanding the differences are cup and hub. Can a prop shop put the cup in it so its the same as a mirage plus?
I have twins and have the LH mirage plus but only the mirage for rh, Revs higher on the non plus which makes sense.

Yes, a good prop shop can do wonders...I suggest sending BOTH your LH and RH to someone like BBlades or Dyna Prop, etc and asking them to match, giving them your expectations.

cool, thanks for the encouragement. I use new england propeller, I'll give them a call tomorrow. Do you know what kind of price a shop would charge to cup it ?

No, sorry...I don't the, only prop I ever had 'lab finished' and re-cupped was done gratis by the dealer I bought my first Baja from. I would SUSPECT it to be $200 - $400, but I am sure others far more knowledgeable than I will chime in soon.

ok thank you

Weird huh ? At one point 23” rh mirage + props seemed to be as plentiful as bbc boats.

yes I agree.
