I’m looking to change props on my 353 Fastech. Currently running HP 500’s carb with Stock bravo I drives and 30p 4 blade Bravo I props. Want to move to a 28p 4 blade prop. Which prop would be the best for my application?

Prop 1:
Hydromotive 4 blade? if so what pitch to get me where a 28p bravo I is? I’ve been told these props work well and are made for boat with stepped hulls?

Prop 2:
Bravo I 4 blade 28p labbed balanced

TIA for any input

The reason I want to change is because the 30’s are to much prop. Only bringing the motors to 5,000 - 5100 rpms. When they should be getting to 5,500 5,600 rpms. And I know the hydromotive’s are “like” a cleaver style and want to know if they would work better than the bravos’s. I had the P-5x on my 33 Outlaw and theybworked great. But have been told unless I have power upgrade 5 blades is a waster. But I had the same motors in my Outlaw as I do in my Fastech. So this is why I’m seeking advice

My current 30p haven’t been labbed yet. Would it be best to have them labbed and stick with what I have? My 33 Outlaw had the same motors and at WOT was right at 5400-5500 rpm’s running a solid 83mph.

I also should mention that the boat has MSD ignition.

Thanks for the advice Griff.

I know this thread is a little older but if you are still in the market I have a set of 28p bravos that we’re labbed by BBlades for a 353. Props are in great shape. Tried them on my 292 and they have a little to much cup for my small blocks to turn above 4700 rpm.

If you still need email me. [email protected].

thank you for the message. I sent my 30p’s out to cutting edge over the winter and had them labbed and reworked. Made a world of a difference. If you’re on any of the boat pages on Facebook I’m sure someone will scoop those up from you.
