BUKH VGT 400

BUKH HIGH OUTPUT DIESEL MARINE ENGINES

DURABILITY, DIESEL ECONOMY AND DEPENDABLE POWER ARE SYNONYMOUS WITH THE NEW VGT-SERIES

All BUKH VGT Common-Rail engines are based on the 6.6L V8 configuration and are designed to be as compact and light weight as possible while maintaining durability and serviceability. The BUKH VGT 400 is intended for medium to high speed vessels and has a light duty rating (Medium Duty as option).

Laptop based diagnostics tool is available for VGT engines. J1939 and NEMA2000 CAN communication.
