The 6AYM-WST is the continuous-duty-only (C-rating) member of the WST/WET pair, a 6-cylinder 155x180 mm, 20.379 L turbocharged diesel rated 485 kW/659 mhp at 1900 rpm with unlimited annual operating hours. It shares block, cooling and lubrication specs with the 6AYM-WET but uses the dedicated YX-181/YX-180L marine gearboxes rather than the YXH series.
