With Yanmar propulsion diesel engines we have two goals to achieve. One is to give you a safe and economical user experience when you are navigating at sea. The other is to let our engines be as earth friendly as possible. We believe these two goals go together very well.

Complete line of medium-speed marine diesel engines

Over the last 100 years, we have continuously adapted our operation and manufacturing processes to reflect our believe. This has resulted in a complete line of variable medium speed marine propulsion solutions from 368-3310 kW (1500-620 rpm) designed specifically for the challenges of commercial marine applications.

IMO Tier II standards for Yanmar marine diesel engines

Our medium speed diesel engines are certified to meet more stringent IMO Tier II global emissions standards. Yanmar has employed systems that improve the fuel consumption and smoke generation in addition to reducing NOx,CO2 & SOx emissions.
