VGT 500

373 bkW (500 bhp) @3500 rpm

All Marinediesel 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 VGT500 is intended for light, very high speed vessels and has a light duty rating. Laptop based diagnostics tool is available for all VGT and TSC engines. J1939 and NEMA2000 CAN communication.
