1991 thru 1995 – 0D469859 Thru 0F679999
1996 thru 1997 – 0F680000 Thru 0K999999
1998 and Up – 0L100040 And Up

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’s Bravo 3 outdrive 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.
