Mitsubishi Description

Large bore Mitsubishi commercial marine diesel engines provide reliable power for tugs, push boats, trawlers, ferries and other vessels subject to continuous heavy load operation. Models are available from 429 to 1,676 hp. Around the globe, Mitsubishi engines have earned a workhorse reputation for economy, performance and longevity, while operating continuously in some of the world’s harshest environments. Their long stroke and low compression leads to less stress on the engine, maximizing time between overhauls. The benefits include less down time and lower maintenance costs.
