Navegação Silenciosa

Quiet Ride.

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.

Razões Repower

Repower Reasons.

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.

Pico de Desempenho.

Peak Performance.

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.

Design Intuitivo.

Intuitive Design.

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.

Resistência a Corrosão.

Corrosion-Resistance.

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.
