Your engine. My job.

1163 engine

The story.

Founded 1999 in Palma de Mallorca, Diesel-Doc is your reliable service partner for MTU engines in the Mediterranean Yachting world.

With more than 25 years of experience in dealing with all kinds of MTU engines from Series 099 up to Series 1163 it's a matter of course to provide you a high professional service and fulfill all your wishes. My company's philosophy is based on quality, innovation and service, thereby providing my clients with efficient and integrated solutions and complying to their needs at all times.


Before I took over the company from “Ecki” in 2015, I worked 24 years for MTU Friedrichshafen.

Starting with an apprenticeship in 1990, I moved on to become a service engineer in 1994. The following 10 years I worked mainly on marine engines on ferries and military vessels all around the world. In 2003 I became an instructor at the MTU Training Center in Friedrichshafen, where I trained customers, distributers, service dealers and MTU service engineers on engines like the Series 099, 183, 2000, 396, 4000, 956 and 1163 up to a major overhaul QL4 (W6).


Your engine is my job.
