Marine propulsion systems often rely on robust diesel engines to ensure reliable operation in various sea conditions. The 9LM25C2 engine is a powerful solution designed for such applications, featuring a 4-stroke configuration with a bore of 255 mm and a stroke of 400 mm, delivering a continuous power output of 2880 kW at 750 rpm. It supports both heavy fuel oil (HFO) and marine diesel oil (MDO), making it versatile for different operational requirements. The engine is designed with a reduced number of components, approximately 40% less than its predecessor, which enhances reliability and reduces maintenance needs. Common areas for inspection and potential failures include the cylinder liners, piston rings, fuel injectors, turbocharger, and valve timing, each requiring specific checks and maintenance to ensure optimal performance and longevity.

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.
