Durable and PowerfulDesigned for sterndrive and inboard applications.
Features may include:
Quiet Ride.The high-pressure common-rail fuel-injection system not only ensures fuel economy, it also minimizes Noise, Vibration and Harshness (NVH), along with smoke and odor – the undesirable factors many boaters associate with yesterday’s diesels.
Repower Reasons.The lightweight, compact design of these diesel engines makes them ideal drop-in replacement power packages for many older, fuel-guzzling gasoline engines. Mercury’s full range of drives offers outstanding versatility to owners of sterndrive-powered boats.
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.
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.
