Raised my motor, but questions...

Yes, the extra blade alone on a 4B will add extra stern lift, although blade rake and how it's cupped also affect stern lift. If your Vortex is a 4B version, you might get more than 200 rpm/inch of pitch with it. The Vortex is an excellent prop; it's comparable SS version is the Apollo, which would probably slightly larger in diameter for the same pitch.
