nag_vgt450All 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 VGT400 is intended for light
high speed vessels. Laptop based diagnostics
tool is available for all VGT and TSC engines.
