Unhappy Which prop: Mariah Z275 Davanti

Hey guys,
I bought a Mariah some time ago. I am very happy with it!
When I bought it there was a Mirage propeller. The size of the propeller was 21 pitch. He easily reached 4600 rpm without a trim. With trim the boat easily reached 5000 rpm. I then tested a 23 pitch Mirage. The tour without trim is now 4100-4200 and with trim I get 4600-4700 rpm. The boat does not go faster with a 23 pitch propeller. With a 21 pitch I reach 65 km per hour (40 MPH) and with the 23 pitch 62 km per hour (38 MPH).
The Mariah Z275 Davanti must be able to reach 80 km per hour (50 MPH).
The engine is a mercruiser 7.4 liter Bravo 1 with 330 hp.
The boat weighs about 6100 LBS.

Do I have to take a 3 or 4 blade screw? For example a Bravo 1 22 pitch propeller?
