Working together with the perfectly matched DPH Duoprop drive and the Electronic Vessel Control system, the package offers exceptional diesel performance combined with low emissions.

High performance

Immediate response and high performance is matched by lower amounts of noise and vibrations further reduced by the balance shaft and the optimized engine suspension.

Compact and robust

The engine is extremely compact for its large swept volume. The rigid cast-iron cylinder block and cylinder head, balance shaft, and exactly controlled fuel injection gives excellent onboard comfort.

Unique Marine Torque

The unique marine torque of the Volvo Penta diesel engines stands out among the competition by offering increased load-carrying capability, rapid acceleration, and the ability to maintain a high cruising speed, irrespective of load or sea state.

Low fuel consumption

The high-tech fuel injection system combined with the advanced transmission and the Aquamatic Sterndrive make the engine highly fuel efficient.

Electronic control systems

Volvo Penta offers two type-approved systems for on-board electronic control. Electronic Vessel Control fully integrates the engines, electronics and a range of optional features. Marine Commercial Control System is an open system that is easily integrated into the ship’s control system.
