The new VETUS D-Line common-rail engine is ideal for heavy displacement boats. It is slow running and exceptionally smooth, making him the engine of choice where long distance cruising is involved.
Based on the quality of the well-known Deutz engine blocks, they are exceptionally reliable and durable.
This is in conformity with the new RCD2 emission regulations. Extremely suitable for power hydraulics on board.
The engine has a CAN bus system with a SAEJ1939 protocol but can easily work with NMEA2000 systems on board as well.
The new VETUS D-Line engine now has a water cooled top cover in order to reduce the heat in the engine room but also to reduce the engine noise of an already quiet engine block.
This top cover can also be used as a step. Other features we have added to the new D-Line engines are: smaller air filters in order to save space in the engine room.
New exhaust manifold insulation, high output alternators as standard (160 Amps) and a 2nd alternator as an option.
Electric sump pumps are fitted as standard. Options such as a calorifier /hot water tank kit, PTO to install a hydraulic pump, fly-bridge instrument panel or trolling valve,
can be ordered separately but will be installed on the engine when ordered as a complete package.
