If you own an older set your model may well appear as MDKB’X’ and not MDKDK (for example), the set will be the same, the latter D simply means it meets new emission standards regulatory in the US. Please call for further details.

System Design and Installation – Our electrical and engineering expertise enables us to design, supply and install AC or DC generators plus associated power distribution systems to cope with the power you need on board today.

Commissioning – Ensuring your generator is installed correctly is paramount to your warranty and the use of the machine. Installation requirements are very stringent, we are able to offer advice if you or an independent boat builder are installing the unit and we are available to undertake commissioning to ensure your set is signed off.

Service and Repair – We can test, maintain and repair existing generator installations and offer a similar winterisation process to that for the vessel’s main engine(s).
