Seapower Marine have been a 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 parts and service dealership area covers Norfolk, Suffolk, Essex and down to St Katherine’s Dock. However, we are able to offer Cummins support on HMLD (High, Medium and Low Duty) engines and the complete Onan range outside of these areas, including overseas.
All of 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 diagnose 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 and Cummins QSB5.9, 6.7, QSC8.6, QSL9.0 and QSM11 engines.
In 2018, Seapower Marine were appointed one of four UK MSD’s (Marine Specialist Dealers) for new engine and generators sales. We offer Cummins sales and support on HMLD (High, Medium and Low Duty) engines and the complete Onan range throughout England.
If you have an Cummins engine from 2007 – 2011 which is a Cummins Mercruiser Diesel we can still provide you with technical help and service parts where available.
