Default Adding pitch?

How much pitch can be added to a prop? For instance, if you have 27 pitch props, and add blowers, can you pitch the props you have up to 31/32?

We can change the pitch one inch on a SS Bravo Stern Drive propeller.

Actually you can add a couple inches but the root pitch won't change because it is cast or welded into place.

We are comfortable with one inch adjustment up or down. there are also cupping changes that effect rpm and indeed change over all pitch.
