Depends on what rpm you are getting with the 23s. Your current props probably have a lot of slip. That will decrease with four blades. 22s will keep about the same rpm at WOT, or maybe increase a few. 24's will drop rpms by about 200

Well honestly I don't know what rpm I turn with the 23s...haven't had the boat in the water yet. The 23s are chewed up..so looking at new prop options. I've never had luck with 3 blades on any boat I've owned so I'm just going to go with 4 blades on this one too. I believe the mirages are stock props on a 311..

Yeah my boat came with mirages and they suck. Running 23" Rev4's now and love them, but they run about the same as a 24 Bravo. I think your boat should run low 60s if its a Bravo boat. Go with 24's since 330s don't like a lot of rpms

Bought them from a 311 owner with stock 330s, he went 64
I had some work done on my 330s and would go 67.1 @ 5000 with stock 24s turning out.
For reference even used the same props with 502 mags later and went 72 @ 5300
I'll message you
