This maritime equipment falls under the category of marine propulsion engines. The MaK (Caterpillar) 9LM25C-GS-50Hz is a powerful diesel engine designed for marine applications, offering reliable performance and efficiency. The 9LM25C-GS-50Hz features a 9-cylinder inline configuration with a 255 mm bore and a 400 mm stroke, operating at 750 RPM. It is capable of generating 2700 kW of power and can operate on HFO/MDO fuel types. The engine is designed to comply with IMO Tier III emissions standards, ensuring environmental compliance. Common maintenance issues include cylinder liner wear and overheating, piston ring wear and carbon buildup, fuel injector fouling and carbon deposits, turbocharger damage from high exhaust backpressure, and valve timing problems and deposits on intake/exhaust valves. Regular inspections and maintenance checks, such as checking for smoke development, measuring piston force, and inspecting exhaust pressure, are essential to prevent these issues and ensure optimal engine performance. For detailed specifications and further information, refer to the manufacturer's datasheet available at the provided URL.

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.
