Mercury Marine proudly introduces the latest evolution of its marine engine – the Mercury Diesel 4.2L, compliant with RCD II emission standards. This advanced engine is now available in the European Union markets.

Key Features and Specifications

The Mercury Diesel 4.2L (RCD II) is a six-cylinder, in-line engine with a 4.2-liter displacement, equipped with a turbocharger and aftercooler. Thanks to the Common Rail fuel system with electronically controlled injectors, the engine ensures precise tuning of the air-to-fuel ratio. This results in improved acceleration, higher top speeds, and greater efficiency.

RCD II Compliance

The new Mercury Diesel 4.2L fully complies with RCD II emission standards. This was achieved through modified fuel injectors and advanced electronic engine control systems. The engine is compatible with both conventional diesel fuel and HVO biofuel, enabling a reduction in particulate matter (PM), nitrogen oxides (NOx), and carbon dioxide (CO2) emissions.

Performance and Power

The engine is available in two versions:

  • 270 HP (201 kW): Maximum torque of 603 Nm at 2600 RPM and a fuel consumption of 60.6 liters per hour.
  • 320 HP (239 kW): Maximum torque of 703 Nm at 2600 RPM and a fuel consumption of 71.9 liters per hour at full load.

Advanced Technologies

The Mercury Diesel 4.2L is fully compatible with Mercury Marine’s Next Gen DTS and JPS Precision Joystick systems:

  • DTS (Digital Throttle & Shift): Ensures smooth gear shifting and immediate throttle response.
  • JPS Joystick: Enables precise maneuvering of the boat, enhancing user convenience.

Corrosion Resistance and Ease of Maintenance

The engine features a closed water-cooling system, increasing durability and reliability. Additionally, Mercury SeaCore® technology provides maximum protection against corrosion in saltwater environments. Maintenance is simplified with top-mounted fluid reservoirs, a self-draining oil filter, and an easily accessible oil level indicator.
