How would the stock bravo3 30" props compare to the new bravo3 XR 27" props behind an HP525 bravo3 2.0R combo...the boat is a heavy 25" deep vee Formula 252LS?

I think the XR drive has the same 2.0R and the 27" props are the largest offering with the HP525?

Does that mean that with the efficiency of the new 27" XR props that they would pull similar WOT RPM's than the regular 30" duo props?

I can pull an indicated 5,150 RPM's at WOT with a cupped 30.5" duo prop and I am looking for an extra 200 RPM's at WOT....that is why I am curious about the performance of the new 27"XR props.

The duo prop must be some kind of a mystery science as there seems to very little information out there on how they function and/or how to tweak them.

Any input is appreciated.

Thanks,

Jamal
