Large Engines: General Information

The Large Engines Department is responsible for marine propulsion engines and for marine auxiliary medium speed diesel generators with a power range up to 3310 kW.

Yanmar’s large engines are used in a wide range of applications like small/large cargo vessels, tug/workboats and fishing vessels. In particular our medium speed propulsion and auxiliary engines have acquired a special reputation for reliability and durability.

Large Engines can be divided into three product groups:

The medium speed engines are designed to use marine diesel oil and heavy fuel oil up to 700 cSt. Yanmar's creative technology achieves low fuel oil consumption and low NOx emissions at the same time. Our engines comply with the latest IMO NOx regulations.

Application possibilities

Large Engines are produced in Amagasaki, Japan, and delivered directly to shipyards all over the world.

Large Engines can be divided into two product groups: Marine Propulsion Diesel Engines (= propulsion engines) and Marine Auxiliary Diesel Engines (= generator engines).

Activities concerning marine engines for yachts and small craft are concentrated in Yanmar Marine International.
