Do you 35 flat bottom guys run Bravo1 props or Hydromotive?

5.6% slip with 1.36 gears and 6000 rpm.... Good luck

Phil it was 9500ish for the boat.

I have a set of both the hydros are a couple miles per hour faster and are fun to drive use mostly for poker runs and the bravos give me a better cruise speed at a lower rpm mine turn out.

when we raced the konrad fountain of youth it was 9260 lbs hanging on the crane with nothing in it and 30 gallons of fuel in each tank ready to race. that was a 86 10 meter. that boat and my 92 35 prefer hydromotives.

Must have been on the Pamlico

i cannot wait to see what mine will run once motors are done....im hoping 80mph :cartman:

What HP are you running and what size Hydros?

What are you putting in for engines?

509's Canfield heads, crane 168811 cams should be 620 or so

Bravo boat? Will definitely run over 80

Mine is a solid roller....244/248 -649/644 on a 111

Yes braves, will run 80 until a drive breaks...
111 lsa or icl?

I run 28 Hydro Q4's,, I use Amsoil 75/110 Severe Gear Synthetic gear oil,
she runs 83-85 on gps depending on chop, wind, load etc.
I have run my Bravo 1 drives 9 seasons now without a failure, I just recently refreshed them and the gears/bearing were in great cond.

Tell us about your power plants....please...

540 Merlin3 blocks, Dart Pro1 CNC'd alum. heads, Dart port matched intakes, Eddie Marine Thunder exh.,, MSD ign. w/the black bushing,, 10 qt. oil pans w/ scraper windage trays, H beam rods, JE pistons, Holley 9022 ,800 cfm carbs. dialed in w/ several jet changes, .600/.610 Howards roller cams degreed in, 35 degree total advance.,Champion Racing spark plugs changed at 30 hours,, 8mm plug wires, big oil coolers w/thermostats, 140 degree water thermostat, no circulating water pump just a crossover.
Just the usual maintence stuff to keep her running in top cond.
Bravo1's ,1.50 use Amsoil 75/110 Severe Gear oil., 28 Hydro Q4 props

Nice!

so Hydromotive seems to have an edge for prop of choice...which Hydro specifically?

power is 509's, Merlin cast heads, Edelbrock intakes, Holley 850's...estimated HP is slightly above 500 each. pushing through XR's, 35 Fountain, non staggered flat bottom

Call Hydromotive tell them what you have so they can figure which is best, also, they have an exchange program if you want to try a couple different props.

Nice power 253 !

My engines are similar. 496CI ,Dart Pro 1 alum heads, Solid rollers, 10.5:1 comp, 1050 Dominators on Dart intakes, CMI headers.They made 625HP... Im hoping for 85MPH...Just bought a set 30P Bravo1 props.

Nice setup, 30P Bravo1 is equal to 28P Hydromotive, but you need to trim the Bravo's more, and the Hydro's are a sternlifter to help get the heavy rear end lifted a bit for less drag, let me know how the Bravo's work out.,, I will take a guess and say 80-82 on gps.

While not a 35 , but a straight bottom 38 with #4's. I got 96.6 out of it this day. had 150 gallons of fuel on board. 17x28p props. 1.49 ratio. 6200rpm. Twin 800's. https://www.youtube.com/watch?v=DtWGMAdeKbU&t=2s

Dang That is moving!!!!! looking good!!!! I just bought a pair of B&M 250's so I'm hoping for 90 this summer. I was running 75-77 last summer on my flat bottom 35 so lets see what happens.

Nice, I would like to have a 38 someday.

Yea me too ! must be nice to be rich !!! lol

That is nice mild how many pounds of boost are you seeing at 6200rpm

Joe that boat is humming along pretty damn good !!! Sounds great. Love the race hatch. AA+++

right about 8psi. Twin 468ci, 420 B&M blowers with chillers, 8:1 static.

I just dont know how you get those bravo's to live.....:angry-smiley-038:

Who has bravos ? :cartman:

Lol, when i first got the fountain, one of my buddys was cracking jokes , said "when they stop making those drives, 1985" ......being that he owns a 42 with 525efis, and broke several XR's, my only reply could be "yes, but how are those new modern drives working out for you " :)

That looked like a LOTO shore line ??

Yes, yes it was :)

You just have to love any time you can go for a good high speed rip and still have both your props spinning when you are done

Put the The 250 b&m blowers on mine Did not change anything else and the best I've seen is 88 Mph at 6 pounds of boost . I just bought intercoolers for it so next year should be alittle faster

I think I should just get rid of my 32 ans save you all the trouble.
