Marine Generator Sets

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.

M 32 C Marine Generator Set

The M 32 C was introduced in 1994 in 6, 8 and 9 cylinder versions and is outstandingly suitable as a generator prime mover for electric power on ships. The robust design and moderate speed permits unlimited, continuous operation with heavy fuel oil. In-line engines – completed with generators – are mounted on a common base frame. The engine and electrics are tested prior to delivery. This ensures trouble-free installation and commissioning.
