Welcome to MarinedieselThe Marinediesel brand VGT engines are manufactured by MD Powertrain in Ängelholm, Sweden.

In 1997 Marinediesel Sweden developed the first true direct replacement diesel for gasoline/petrol V8 marine I/O or inboard engines as well as one of the most durable yet lightweight commercial engines on the market. This model was and is based on the GM 6.5L V8 diesel engine, that was renamed to Optimizer 6500 when it was taken over by GEP in 1999, the base engine has one of the most impressive commercial and military histories of all engines and is used in the military Humvee and Hummer H1 to mention a few. By 2010 Marinediesel released the new VGT series based on the GM 6.6L Duramax engine in power range from 350-600hp.

Marinediesel also have a newly developed 500cc 14hp monoblock diesel outboard for the commercial market.
