Talking Merc prop change

Hey , has anyone ran a tempest prop on there I/o ? I have a 4.3 sportfire and I found one cheap . How much difference from my 13 3/4 x21. It's a 23 pitch and I need to tame my rpms down from 5200 .

It should certainly drop them...I can't speak to how many, but you should see a decrease.
