I think if you raise the engine another hole, you will gain another 200 rpm's at WOT just from less drag in the water.
Keep in mind we do the WOT testing because if the engine reaches it's sweet spot (5700-5800 rpm's for the F90) running solo and light, it will run efficiently at all various speeds with passengers and gear.
Now if you run most of the time with two guys, 50 lbs of ice and gear, I would drop down 2" of pitch in the same model of prop.
