Commercial Propulsion Engines

Industry-leading technology allows Caterpillar to create the most reliable commercial engines for a variety of applications. From tugs and container vessels to yachts and sport fishers, Cat and MaK engines have demonstrated their efficiency countless times. With remarkable reliability and durability, these engines will exceed your expectations for decades.

VM 32 C Marine Propulsion Engine

The M 32 C V-engine was introduced in 2000 in 12- and 16-cylinder versions. With a bore of 320 mm and a stroke of 460 mm, it covers a power range of 6,000 - 8,000 kW in the 720 and 750 rpm ranges. The engine is designed to meet not only the demands of the marine market but also those of the stationary electric power generation and oil & gas industry. The consistent application of the MaK long-stroke engine design and development along with the incorporation of as many in-line engine components as possible is clearly and impressively demonstrated in the external configuration - a compact, simple and clean design.
