353 Fastech Prop change advise
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

HP500 WOT range is 4800-5200 rpms and rev limiter is at 5350rpms. Have your current 30's labbed.
353's already run flat. Q4's will give too much stern lift and Q4X's will be about the same as Bravo props.

IMO, getting your current 30's custom labbed is the best option.
