About Mitsubishi
Mitsubishi has its origins in Japan, where the Mitsubishi business was founded in 1870. Mitsubishi Heavy Industries later developed into one of Japan's major manufacturers of machinery, engines, ships and industrial equipment.
Today, Mitsubishi marine diesel engines are manufactured in Japan, with Mitsubishi Heavy Industries producing engines for marine propulsion, power generation and industrial applications.
The Mitsubishi marine installed base ranges from compact auxiliary engines to larger high-speed and medium-speed propulsion engines used aboard commercial vessels.
Different models and versions can use different fuel, cooling, turbocharging and control arrangements. The complete engine designation and serial number are therefore important when identifying replacement parts.
