my backup is a 3 blade 17P Mirage+. not solas just looked. 4 blade and don't look back imo. I get 6200-6300 RPM WOT 2 guys, 3/4 tank @130 gallons full, this is at 275HP as I bought a CPU and switched it into my Verado once off warranty. at 250HP I was barely 5800-5900 with the same 17P Rev 4. MY 23SC is on the heavy side.
Make sure the engine height is correct. Bunch of tips over here applicable to any OB, you probably already knew all that though. I spent a few minutes with my head hanging off the back at 40+kts a couple years past though
. Make sure your wheelman likes you.
