MerCruiser Sterndrive leg

Bravo I

MerCruiser's single-propeller performance sterndrive, rated for petrol engines up to 600 hp and diesel up to 370 hp in single, twin or triple installations on boats exceeding 100 mph.

Mercury's own current spelling is 'Bravo One'; the roman-numeral form Bravo I is the older and widely used rendering, and is the spelling already on this make's drive row. The drive was designed to handle big-block engine power and replaced the heavy TR/TRS drives for high-performance sterndrive work, its cone-clutch shifting removing the separate transmission the TRS required. Distinguishing features are an extended-length torpedo to cut drag, a deep skeg giving a large rudder area for steering response at speed, and dual water pickups so large engines stay cool at high speed. MerCathode electronic corrosion protection and an in-hull power trim pump are standard across the Bravo range. Bravo One X and Bravo One XR are catalogued with it as heavier-duty members of the same family and are loaded as their own rows.
