Equipped with an 8-cylinder, 4-stroke non-reversible design and a bore of 200 mm and stroke of 300 mm, the MaK M20-GS family of engines operates efficiently in marine environments. The MaK 8LM20-GS-60Hz specifically caters to high-power requirements with a nominal power output of 1440 kW at 900 RPM, fueled by heavy fuel oil (HFO), marine diesel oil (MDO), or liquefied natural gas (LNG). This engine family is designed for both diesel and dual-fuel operations, ensuring flexibility in fuel choice while meeting IMO Tier II standards in diesel mode and achieving the more stringent Tier III requirements when running on LNG. Regular inspections should focus on areas such as crankshaft bearing wear, piston ring liner conditions, and turbocharger health to maintain optimal performance.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
