Bravo One X/ Bravo One XR

Great performance starts with heart. Bravo! Single/twin/triple applications over 100mph for gas engines up to 600 hp

The Bravo One drive delivers superior performance with best-in-class shifting. Its exclusive performance torpedo design and dual water pickups allow for speeds topping the century mark, with exceptional handling at high and low speeds.

Bravo Two X

Handle the biggest boats with authority. Twin applications up to 55 mph for gas engines up to 450 hp

The unique Bravo Two drive has an unmatched ability to maximize lift and thrust for cruisers and houseboats without breaking a sweat. Due to the girth of the gearcase, Bravo Two is capable of accommodating a huge 20-inch diameter prop with deeper gear ratios. This allows the Bravo Two to deliver high thrust around the dock, quick planing and improved fuel economy-putting you in control. maintenance-free hinge pins allow for easy service without having to pull the boat from the water.

Bravo Three X/ Bravo Three XR

Efficient.Maneuverable. Unbeatable. Single/twin applications up to 65mph for gas engines up to 525 hp

The twin-prop design says it all. Whether in a single-unit or twin-unit application, the Bravo Three is an efficient drive built without compromise. Perhaps it's the best-in-class shifting or its counter-rotating propeller design - enabling agile handling in reverse for precision maneuverability. And the greaseable gimbal bearing makes for an easy ownership experience-allowing for service without removing the drive unit. The Bravo Three X drive, standard on big block 8.2L high-output engines, is a superstrength drive with high performance attributes.
