Seapower Marine has been a main Cummins Light Commercial and Recreational Marine Dealer since 2007. Over the years, we have built up a wealth of knowledge and experience in dealing with Cummins engine and Cummins Onan generator installations, warranty work, servicing and part supply. Our dealership area covers Norfolk, Suffolk, Essex and down to St Katherine’s Dock.

Our staff are trained regularly by Cummins UK, enabling them to help you identify service parts, give advice on fault diagnosing, warranty issues, down to helping you diagnose more serious operational issues and choosing the right new engine or generator. We have Cummins test generators onsite, enabling us to assist with the diagnosis and replicate any faults. We also offer a Cummins Onan PCB check and configuration service, for further details please call the office.

We hold large stocks of the most common service items for all Cummins Onan MDK and MDD generators, incuding parts for the RV market. We hold a limited range of gensets at our site, non-stock sets can vary from 3 days to 12 weeks depending upon the configuration so please call us with your requirement.
