This marine engine is commonly found in large ships requiring reliable and efficient power generation, particularly in applications where Heavy Fuel Oil (HFO) is the primary fuel source. The 6LM46-GS-60Hz engine, part of the M46-GS family, delivers a rated power output of 3960 kW at 900 rpm, making it suitable for driving propulsion systems or generators. This engine operates on a long-stroke configuration and is designed to handle various fuel types including HFO, MDO, and even dual-fuel capabilities. With a bore and stroke of 460 mm and 580 mm respectively, it is a robust piece of machinery that can operate within a flexible speed range, although the typical operational range is between 425 and 600 rpm. The engine's legacy status, with production ending in 2022, underscores its historical significance in the maritime industry. Regular maintenance checks, including inspections for camshaft wear, crankshaft bearing conditions, cylinder liner wear, and exhaust valve integrity, are critical to ensure optimal performance and longevity.

Free of charge — send us your request for MaK (Caterpillar) equipment. Our team checks it and replies by e-mail.

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.
