Default what drives for 650 -750 hp

I am wondering if on a 38 foot boat with 650-750hp twins, is there a bravo style drive that you would be comfortable with. If not what would you be comfortable with through a bravo style drive, ie XR, Imco, Max, Teague etc...

Bmax is supposed to be good thru 800 or so.
Max is a tough unit, but that's a lot of power for stock Merc sized gears. They say their new billet drive has been tested with 1500 horses. You're sort of on your own though since its a new drive.
Konrad is coming out with a shiftable Bravo replacement. Their stuff is beefy. They will also fit their proven nonshifting drive on an extension box that houses the tranny. I like that idea but its pricey.

MAX, Teauge, or TMP. TMP runs Bravos that they modified behind 800-850 HP in a 38 Fountain. I am like Mcollinstn for the Konrad's in boxes with transmissions.

How much horsepower will the Konrads hold? And what tranny's are they using?

I'm running a pair of 700 hp motors in front of Konrad 540's/Huber 925 trannies. We racked up 110 hard hrs on her last season with no problems at all. These things are tough!

Biggus

I have been following your story here on OSO. I currently have a 29 Progression. Was considering the Konrad because of the tranny in the box. For the simplicity of not having to moe the engine foward. But I am planning 800+hp. What will the Konrad 540hp hold?

I am with Biggus on the Konrads. Did they show their shiftable that is rumered to be coming out at Miami? I have seen the inside of these things and they are SUPER beefy but from the numbers that Biggus is getting it seems that they still have them running the boat at faster speeds. We will really see how his goes this year with the new lower.
