In marine applications requiring robust and reliable power generation, the 6LM25E-GS-60Hz stands out as a high-performance solution. This engine is part of the M25E-GS family, designed to deliver exceptional efficiency and durability. With a power output of 1890 kW at 900 RPM, it can also generate 1796 kW of electrical power at 60 Hz, making it suitable for both propulsion and generator sets on board ships. The engine’s L-configuration with six cylinders and a bore of 255 mm and stroke of 400 mm ensures smooth operation and high torque. It is capable of running on heavy fuel oil (HFO) or marine diesel oil (MDO), with optional equipment for HFO, enhancing its versatility in various operating conditions. The 6LM25E-GS-60Hz features a 4-stroke design and incorporates advanced technologies such as turbocharging and selective catalytic reduction (SCR) to meet IMO Tier III emissions standards. Regular maintenance is crucial; common issues include cylinder liner wear and overheating, which can be mitigated by inspecting the liners for wear and ensuring proper cooling system function. Other areas of concern are piston ring wear, fuel injector contamination, turbocharger damage from high exhaust backpressure, and valve timing problems, all of which require periodic checks to maintain optimal performance. The 6LM25E-GS-60Hz is actively in production, building on the legacy of the M25C series introduced in 1996, with significant improvements in component reduction and efficiency.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
