Seapower Marine is the main Cummins UK dealer for marine engines and generators. The Cummins marine diesel engines are available from 4.5L to 15L as both propulsion or auxiliary. We also supply generators up to 99kW including the Onan Quiet Diesel product range. We have been working with Cummins and their products since 2004 and we are dedicated to supporting the brand and its customers. We are passionate about the Cummins range and work hard to supply from stock: main equipment, parts, service work and offer technical expertise around the world.

We supply most commercial craft including passenger vessels, fishing boats, windfarm support vessels, tugs, pilot boats, dredgers, inland waterways, charter yachts and recreational vessels.
Our warehouse holds extensive stocks of genuine service spare parts for propulsion and auxiliary engines and Onan generators. Our fully equipped workshop undertakes upfit work, spraying, repairs and overhaul work. We keep marine diesel engines and Onan generators in stock from our UK warehouse.
