Bravo 3 Drive - max top speed
 

What is the max top speed a boat can go with a Bravo 3 drive ?

I heard about 60 MPH is the limit ! ?

onlly limited by power I'm sure

I just re-rigged and sold my WPM Warrior 28' cat with a 700 hp blower motor, Bravo 3, 1:5 gears, 30 pitch props, nose cone, on a stand-off box, the best mph on GPS is 78. I'm going to try 1:36 drive in a couple weeks. I'll let you know.

This thing is a rocket out of the hole.

Teague said in a powerboat article that the Bravo 3 hits the wall around 60 and takes a lot of hp to get over that. Maybe thats why a 28' cat with 700hp is only going 78mph.

I had a Bravo 3 connected to a Whipple-charged 502 in a 22-foot Crownline. I GPS'ed at 74 one day with five people onboard.

It had the best hole-shot on the lake! :cool:

My Cobalt is HEAVY.. 26'10" it'll do 60 loaded down with 5 people and with no people it'll do about the same. Almost the same performance. Bravo 3's are really a workhorse. The dynamics of the design makes it hard to push over 60. My bow doesn't even rise coming out of the hole... its just straight. I'll have this boat until my kids are done with the watersports and then move on...UP!

what the hell is a braveo 3?

Re: Bravo 3 Drive - max top speed
 

I have BIII's on my .38 Special. It runs 60-61 GPS with a full tank of gas or 1/4 tank. I may have the slowest boat but I get one hell of a hole shot and I'm out in front for about a 1/2 mile :evilb:

Any dual-prop drive will pay an increasing drag penalty as speed goes up - there's just sooo much blade area that you can't get away from it. The B3 lower case isn't the best for high speeds either.
I've got Volvo DPX's on a pair of boats. One is a 38' Formula (heavy - every option) with 600's that will run 75+ any day and almost 80 on a good day. The other is a 28' Batboat with a single 600 that runs in the low 90's. The DPX is considerably more hydrodynamic than a B3, but it's also out of production. (Although there is a pair sitting in my garage....)

The Volvo duoprops are superior to the B3, smoother, stronger(much), more hydrodynamic, especially in heavier boats over 8000lbs.

My early no arch no gen formula 330ss could run a tick under 60 with 330s. Would have been really fun with 502 mags.

They did make an XR B3 to handle the torque of 525. I believe the biggest pitch for a stock blade pitch was 30. Unless you are going to build a custom set of props and max out the HP that a stock B1 upper can handle it's not a cost effective speed solution.

The B3 is great in single engine runabouts in the 15 to 30 foot range. But 60-70 mph is about it.

Would the Black Hawk lower fit on the Bravo 3 upper? I’ve always wondered how they would work on my Velocity..

The black hawk is a 1 piece case, it doesn’t split in half like the rest of the bravos do

There is no B3 upper, the top is a standard B1 with X or XR gears.

We were able to get 87mph with our single engine Bravo 3. It was a 1.5 gear ratio, but I do not recall the pitch of the prop. That said, the prop guy cut a ton off of those big ears to get it spinning faster. We also added a nose cone.

The 33 scarab with DPXs and 600 innovations was very speedy

Perfect setup for that hull.

Have a 2000 226 Cobalt with a stock 7.4 MPI. Corsa silent choice exhaust bravo 3 29P prop with a 1:2 ratio. Best speed 1/2 tank of fuel slight chop. Next speed 63.5 mph on gps
