According to many articals I have read the first thing you should check before having the props repitched is the back pressure on the exhaust.
This is often the cause for a boat not reaching WOT.
There is also issues such the load and how*clean the bottom is.
If the*props were properly pitched when new.* Why is there an issue now?*
It could be issues other than what you are indicating.

I don't knowbut if you have them re pitched and the issue was high back pressure what would the re pitching do to the engine?
Food for thought.
