Repower Prop question

[thebottomfish]

Last year I had called it quits with my old 120 Johnson and found a smoking good deal on a 99 175 carbed Johnson, hooked everything up and she runs great, after sorting out optimal mounting height I'm ready to work on the propeller.
The current prop does okay, runs WOT at normal load at 5100...but it's unmarked, is pretty banged up(aluminum) and I'd like to start fresh.
Any suggestions as far as prop size and pitch?

Hoping someone here might have a similar v6 looper on their V and can tell me what they've been happy with just to use as a starting point.

Or if anyone knows a shop in NJ that can measure my prop that would be helpful as well!!

Thanks!
