Currently running a REV 4 (14.625") & looking for more stern lift. Would the larger diameter (15.25") Bravo 1 or Hydromotive Quad X provide more stern lift?

Would the RPMs change ?

go to stern lifting blade , like a hydro automitve they are stern lifting blade, they are in ohio. they have straight edges not round ear like bravo 1 with are bow lifting

+1 for Hydromotive P5 or P5x.

The Hydromotive QuadIV and P5 will add a lot of stern lift. The QuadIV X and P5X are more of a nuetral lifting prop. More diameter will also increase stern lift.

They recommended the Quad IV (15.5") or preferably the IV X (15."). Said Rpms may drop 50.

I didn't ask & they didn't suggest the P5 or P5X. Seems like the extra drag would slow me down offseting any gains of the better stern lift.
