Kid, shut up already. You couldn't tell a bravo from a number 6, a manifold from a header, a carb from an oil pan, or your d!ick from a blower switch.

An XZ and XR are rated up to 700hp? I beleive, 650 if its not 700. If your easy getting onto plane, get off the throttle when you leave the water, and have a relativity light boat..... you'll be fine! Put that on a 38zr and you'll have a problem. But it on a superboat, activator, lavey and you won't have a problem! Pekerrun, its about time for you to beat it. You're a freakin moron.

He hasnt been active since the 21st . I think you scared him away. Kinda nice not seeing these on every freakin post.

I agree with Park35, I have a 25 Checkmate pushing just over 600 with a B1, Just take it easy out of the hole, otherwise haven't had a problem.

The XR is rated to 650hp. Even with that and with a light boat, be prepared to have new gears installed in less than 100hours. they may not spit teeth off, but they will start to pit and put metal in the oil. Once that happens, you are living on borrowed time. I dont care how you get on plane and how easy you get up to speed, the XR gears will start to go away with that much hp.

I know that everyone and their brother has a story about running 900hp through a stock Bravo 1 for 300 hours with no problems. But that is simply not the norm.

I have a 6000 lb boat with a blown 468 in it with a bravo 1. I'm running a 4 blade 26 bravo prop.I don't stab it out of the hole, although I have pushed into it, I don't just yank it wide open. Mine has about 175 hours of use and no problems so far. I don't run the boat all that hard and haven't seen anything yet, knock on wood...

Ive been more worried about the stock 330 hp coupler i still have on it, I figured I'm gonna smoke it one of these days.

Would like to add that I have drive showers and change the gear oil 3 x a season,was running a 26p or 28 for those 4 years once your gear oil is realy black ,might be time to freshin up

I ran around 750hp in my old boat for years on a B1 with no problems. One thing I was always told was bravo's love high RPM and will live longer in a motor spinning 6000 rpm than 5200 even if the HP and TQ is the same.

I have over 700hp on my bravo 1 its a 598 motor. Use bot three times a week pretty much all year. Spin 6k which is the limit on a bravo. Just be careful out of the whole and you will be fine. Keep your hand on the throttle and learn to feel prop slip etc.

Poke n Run, how much does your boat weigh? I have a 598, 800hp, 798 ft lb tq, going in my 272 Sr1 Formula with a b1 and I am concerned with the weigh of the boat.

You only have 1motor in your 272 ??
