If you are going to cruise at 3500-4000 RPM, what will your torque be in this RPM band? This is a good question to ask all...."when your drive broke, how much torque were you making"? Our MMW Bravo XR's have not broken in 8 yrs but we only have about 650 lbs torque with a 9500-9800 lbs boat (includes crew and fuel).
There are lots of Bravo drive failures with 700+ lbs. torque and 10,500-11,000+ lbs 38' boats. Some large CI BBC's can make 800 + lbs of torque.
Bravo drive specialist, do you think there is a direct relationship between drive failure and the torque made with big CI?

5000 LB single engine. 509 CI with 871 blower. I'm not going to beat it. My current XR has only 60 Hrs. babied with original 575. Thought i'd be better off selling it and up grading in lieu of breaking this XR.

Had a boostpower quad rotor 598ci in a 27 eliminator and broke 3 in a month. Never broke one cruising or while running on the big end, But everytime I would hammer on it from 60 mph it would break while excellerating. The guys at max said the motor made to much torque in the midrange. was running a BBlades bravo 32
