BlackHawks are a great drive. The down side was how they were used by some mfg's. Donzi, as much as I love them, really hurt the BlackHawk program. They did not mount them high enough on the 22 Classic, and they added way too much rocker to the bottom of the hull. This resulted in an ill handling, porpoise prone boat. At any other speed other than WOT, you had to drag some serious tab to keep from porpoising. Other mfg'g mounted them too high, and they had no bite. Scarab did a pretty good job with the P-29 & the BlackHawk drives. The internals are all Bravo, so, with the exception of the gearcase, everything internal is replaceable/upgradeable. I think IMCO used to even make a short version of thier torsional vertical shaft for the 'Hawk.

You need to use the BlackHawk on a relatively small lightweight hull. A little rocker in the back would help out too.

I currently have a 97 Donzi 22 Classic 454MAG 385hp (Stock hull, no rocker) that I just hung a BlackHawk on, with no increase in X-dim. I got a 4 mph increase. I went from 68-69 to 72-73. Over the winter I plan to raise the engine 3" and use an IMCO extension box. I'll post the perf data as soon as I have it in the spring.
