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 43 C Marine Propulsion Engine

Developed to meet the requirements of the cruise ship and ferry markets, this new engine series is the breakthrough into a new class of power. Designed state-of-the-art, engineered to lead. After the successful introduction into the market of four new engine series in only ten years, the extension of the program continues with a further engine - the VM 43 C engine. The 12 and 16 cylinder V-version of the M 43 C doubles the power on offer from Caterpillar to 16 MW and therefore supports new and important market segments and groups of customers.
