Marine Engineering in North Wales

ABC Powermarine is long-established in North Wales marine engineering. Our factory trained mechanics have a wide experience of dealing with almost all makes of marine engines and can provide support for any make of outboard, either in our main workshops at Gallows Point or wherever the boat is, using our mobile workshop.

We are Anglesey's only Mercury Service Centre and our factory-trained engineers offer the full service and warranty back-up you expect for all Mercury and Mariner engines. We are equipped with the full workshop tooling, including the latest G3 CDS diagnostic equipment, enabling full testing of all new generation Four-Stroke, Optimax and Verado engines.

Our workshop tooling includes a dynamometer, the marine equivalent of a rolling road - to ensure that your engine is tuned to perfection. We utilise an ultrasonic bath for cleaning fuel systems to ensure the results you expect.

We are also a Mercruiser Service Centre and a dealer for Mercury Diesel, covering the whole range of sterndrives and inboards. Our CDS diagnostic equipment works with the latest generation of Multipoint Fuel Injection (MPI) engines as well as the Mercruiser D-Tronic and Cummins Mercruiser QSD-series engines.

Our engineering department is able to undertake all aspects of work on outboards, inboards and sterndrives, from regular serving, right through to complete rebuilds and the fitting of new and replacement engines. Please contact us if you require any further information.

We are one of few marine engineering businesses to offer fixed price servicing for all types of engine and can offer this service on-site for most engines.
