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 32E Marine Propulsion Engine

The new VM 32 E engine is designed for our offshore customers seeking the greatest reliability and durability in combination with stability at high power output. The VM 32 E engine extends the output range of our recently announced M 32 E in-line engine above 5 MW and stands out with the same superior serviceability and long maintenance intervals. Additional properties of the VM 32 E are power output of 560 kW/cylinder, 100% PTO capability and a large portfolio of application-driven options. The VM 32 E has an improved power to weight ratio. It is the best solution for engine rooms that occupy fewer frames. Besides, the VM 32 E is a SCR, ready for the new Cat® SCR System to fulfill IMO III exhaust gas emissions.
