Are Bravo 1 props actual ptch what they are stamped or is there any truth to the rumor that they are 1 1/2 pitch less..for example......a Bravo 1 24-4 blade is actually a 22.5...Second...on a 253 Convincer(97)..is a Hydromotive prop better than a Bravo 1...Which has better performance..Thanks

I've heard they are 1" less pitch than stamped.

Assuming you mean a Hydromotive Q-IV vs. a Bravo 1. From my experience the Hydro cause alot of stern lift. On my old 24' Baja it was so much I couldn't trim past it and the prop caused bow steer. Bravo 1's are more of a a bow lifting prop. You likely have a fairly deep x-dimension, so a Bravo 1 would be my vote. Try them out and tell us how it goes. Just my $.02

Yes if you are running for example a 24 pitch Hydro 4 blade you would need a 26 Bravo 1 to turn around the same rpm.

Hydro's are more of a stern lift prop and Bravo's are more of a bow lift prop.

Bravo I's run one inch smaller that marked. A 24 would measure out at 23". Props make a huge difference in your boats performance and each hull will respond differently to a given prop. Even though a Bravo I is an excellent choice for alot a different applications you should talk to someone who has experience with your particular hull and the prop you are thinking of using.
Call Brett at BBlades, he is a sponsor here and knows the shiznitz.

The stamped pitch is the maximum pitch on any one blade. All the others are blade will be less. The 1" less pitch is a good rule of thumb.

I tried every type prop on my old 253 Check. Hydro QIV RH is the best prop for that hull.

call matt and julie at throttle-up in st pete. they will get you dailed in better than anyone
