Repowering my 1993 35 non-step lightning, Dyno @ 540 HP each. Bravo drives. Any advice would be greatly appreciated

Drive ratios? 1:50 or 1:35?

1.50

I have a 92 with 600 hp 620 tq @4800 I have labbed 28 bravo ones. I turn them 5400. You might want to try a 27 hydro motive quad 4. I liked hydro props spinning in better than bravos

What were you running previous ?

23 mirage with stock 425 EFI's, Has anyone heard anything about "PowerTech" ?

You better get on the bblades program

In case you get interested in the 27 Hydromotive QIV's, I have a set labbed by Hydromotive I'm looking to sell.

I use 28 Hydro. Q IV Props on my 35 non step 1.5 Ratio, they work great,

Hydromotives are somewhat the favorite on the single and non stepped 35 Fountains. Before the kumbaya days of Fountain and Merc the Hydros went out the door on most boats.
