I would do a little more investigating if the current prop is that far off from what boatdiesel recommended. However, that may be why you are not getting WOT rpm.
From comments I've read on boatdiesel, it's not uncommon to find a boat propped improperly for a variety of reasons.

I had an inch of pitch taken out of mine per the prop calculator on boatdiesel. I've been told that many times a manufacturer will prop a boat to attain advertised speed which may be overloading the engines, the number one reason for diesel engine destruction according to Tony Athens, a moderator on boatdiesel.
