No matter what type of boating interests you most, Mercury® MerCruiser® can power it better than anyone else. The freshwater closed-cooling system (standard) dramatically limits potential corrosion. In fact, Mercury® is so bullish about the anti-corrosion technology built into these engines, we offer a standard four-year limited corrosion warranty in addition to the three-year limited factory-backed warranty. High-displacement volume and premium MPI fuel injection combine to deliver outstanding acceleration, instant planing and smooth performance throughout the rpm band. Mercury® SmartCraft® Digital Throttle & Shift is standard, providing precision throttle response and effortless steering.
