Crews and engineers on board rely on robust and efficient marine engines to ensure reliable propulsion and power generation, critical for the safe and smooth operation of vessels. Caterpillar MaK’s Cat 3512B engine is a prime example of this reliability, delivering 840 kW at 1800 rpm. This 12-cylinder, 4-stroke engine is part of the M20C/M25C/M32C/M43C family, known for its versatility and performance in various marine applications. The Cat 3512B can operate on a range of fuels, including heavy fuel oil (HFO), marine diesel oil (MDO), and marine gas oil (MGO), making it adaptable to different operational needs. Its design features high-efficiency turbochargers with corrosion-free housings, enhancing performance and longevity. Since its introduction in 1994, over 1600 units have been produced, with the majority used for propulsion and a smaller portion for generator sets. The engine's robust construction and proven track record make it a trusted choice for marine operators, ensuring consistent performance even under demanding conditions.

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.
