Hi John,
I have a 2003 460 with the same power and gear ratio. I get 2670 RPM at 29.6 MPH indicated on the Raymarine tridata.
My props have been reworked by the previous owner and are 28 x 30.6 with 2.25 bore. I just found a scan report from 2011, showing 28 x 32.5, so somebody back then was trying for higher speeds. There were several gear ratios installed in these boats, so prop pitches are all over the map on these forums.

I'd say that's moving pretty good for a 45' vessel!!
