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.

C18 (SRMP) Marine Generator Set

The C18 SRMP is the latest generator and brings commonality with our petroleum products as well as interfacing improvements. We have also taken this opportunity to add new price list options. All engine ratings and emissions certifications are the same, however we have been able to increase the power output of the generator for 12 of the 14 ratings.
