Speaking from experience, if its an injected engine, it starts pulling power at 4900 or so. Put one in a few years back, and found it to be PICKY about propping. If you went a hair low on pitch, it would pull power, a hair to much pitch and it would bog out, but get it JUST right and she would boogy.

The real problem with propping is that there's so much more to a prop than just the pitch, and all of them effect how the engine preforms. You have pitch, diameter, rake, cupping, prop material, type of blade, blade tip, number of blades, and of course, position of the blade in the water, just to name a few. (there are more) And each and every one of those items can and will effect the overall performance of the engine and the boat.
