Mercury diesel-powered engines give you unparalleled durability. Thermostatically optimised closed-coolant systems. Advanced control systems. And ultimate corrosion resistance. These engines are built to go the distance.
Mercury diesel leads the industry in power-to-weight ratios, delivering heavy-duty propulsion in a lightweight package. For you that means quicker acceleration, faster planing, and improved maneuverability. Higher efficiency, too. Another bonus.
Advanced intake systems keep Mercury diesels running easy and clean. None of the harshness or fumes from traditional diesels. And an increase of up to 50 percent in fuel efficiency compared to gas engines of the same horsepower. More reasons to go Mercury diesel.
The high-pressure common-rail fuel-injection system not only ensures fuel economy, it also minimises Noise, Vibration and Harshness (NVH), along with smoke and odor – the undesirable factors many boaters associate with yesterday’s diesels.
The lightweight, compact design of these diesel engines makes them ideal drop-in replacement power packages for many older, fuel-guzzling petrol engines. Mercury’s full range of drives offers outstanding versatility to owners of sterndrive-powered boats.
Impressive acceleration and quick throttle response are delivered by the proven common-rail fuel system, which incorporates a turbocharger and seawater after-cooler. These engines combine smooth performance with key diesel advantages, such as high torque and optimum fuel economy.
A sophisticated Control Module and Mercury SmartCraft compatibility provide complete control over key engine functions. SmartCraft Digital Throttle & Shift (DTS) offers smooth shifting, immediate throttle response and high-tech digital controls.
Mercury diesels feature state-of-the-art anti-corrosion, including a thermostatically controlled closed water-cooled system. Water-cooled engine oil, gear oil and steering fluid decrease engine-room temperatures, extending engine life. The SeaCore® system is available for the ultimate in saltwater protection.
