how much shorter is a Bravo over a B-hawk? I forget . . .
I'm pretty sure it's an 8" difference between the 2.

The reason mercury stopped the Blackhawk program that I was told was you could only shift the drive at 600 rpms which limited the aplications for warranty's. and the Hoss props that we used to run in the 90s on the Scarab were 5 to 10 MPH faster then anything that Merc. had.

can anyone please tell me who made these cleaver props for the Blackhawk outdrive. 732-372-1904. [email protected]
