Main Engine 4-Stroke · Main Engines (4-Stroke)
Marine engineers and operators rely on reliable and powerful propulsion systems like the MaK 9LM25C to ensure smooth operations and efficient performance. This engine is part of the M25C family and is designed to deliver a continuous output of 2790 kW at 750 rpm, running on Heavy Fuel Oil (HFO) or Marine Diesel Oil (MDO). With a bore of 255 mm and a stroke of 400 mm, it features a 9-cylinder inline configuration, making it suitable for a wide range of marine applications. The engine's specific fuel consumption (SFOC) is approximately 183-184 g/kW, and it includes a turbocharger with selective catalytic reduction (SCR) availability. Maintenance checks should focus on the cylinder liner wear and overheating, piston ring wear and carbon deposits, fuel injector blockages and carbon buildup, turbocharger damage due to high exhaust back pressure, and valve timing issues and deposits on inlet/exhaust valves.
