Wich drive is better for a boat weighing in around 9K with say 500 horses? I thought XR's were suppose to be improved on the Bravo One. Now I keep hearing about XR's being destroyed.

no comparisom between bravo one to xr in my opinnion , look at the cost , that will tell you the answer rob .

XR's are much better than a regular bravo 1......but they still break!

Find an X or an XZ, that would be enough.

Get XR's. My XR has grenaded 3 times in 4 years at 700 hp and I baby it.

The bravo1 is good to 700hp...it costs less than half of the xr...u could break 2(I doubt u will)and still be ahead...if u want bragging rights and have extra money to waste get the xr...I have bravo 1's on my 31 and 386 with 260hrs on the 31(525sc's pusing over 600hp) and 230 on the 386(trip.500's) with no problems...just my.02

I thought the Bravco 1 was only rated up to 500 hp. From what you guys have said it sounds like the Bravo 1 set up is good enough for my application. Thanks.

700hp will snap a bravo 1 like a twig. The XR is the best choice for 400-600HP, after that you must be gentle or upgrade.

the torque is what breaks theese drives , thats why teague and boostpower are building theire big stuff with smaller cubic in , the bigger cubes build so much torque that they fry the drives . hope you got a rev limiter running bravo behind anything with some balls !

Get a Bravo X or at least a Bravo 1 with serial # OM or higher. The OM+ year is the year they made some improvements.
