Alpha Generation 2 model was introduced in 1991 and is currently still in production. The Alpha Generation 2 models have been broken into several different Serial Number Ranges as follows:

1991 thru 1995 – 0D469859 Thru 0F679999
1996 thru 1997 – 0F680000 Thru 0K999999

Bravo 1: With a focus on high speed performance, the Bravo 1 sterndrive is used for single, twin or triple engine applications and can produce speed up over 100 mph for gas engines up to 600 HP. In addition to triple-digit speeds, the exclusive performance torpedo design and dual water pickups allow the Bravo 1 to handle high and low speeds well.

Bravo 2: The Bravo 2 sterndrive is designed for twin engine applications and can power a boat up to 55 mph for gas engines up to 450 HP. With a wide gear case, the Bravo 2 is able to accommodate a propeller up to 20” in diameter that propels a boat on plane faster and improves fuel economy.

Bravo 3: MerCruiser Bravo 3 outdrives feature counter-rotating dual propellers that improve propulsion efficiency, speed, acceleration and handling on a boat. The two props are mounted in front of one another and turn in opposite directions eliminating wasted energy from the propeller wash. The Bravo 3 is available in a single or twin engine application and is capable of speeds up to 65 mph for gas engines up to 525 HP.

MerCruiser Blackhawk Surface Drive

The Blackhawk basically has the bravo 1 upper gears and bravo 3 lower gears/propeller shafts, etc. with a shorter vertical shaft in a one piece case. The Blackhawk drive is about eight inches shorter and can be mounted almost 2 3/4 inches above a standard Bravo. The two props maintain the bite at this height, but it takes a good engine to turn all that blade area at idle.
