The powerful heart of a yacht

Yacht enthusiasts can look forward to next-level technology: With the expansion of our MAN Marine high-speed series MAN 175D, we are redefining the term 'high-speed' – an engine that promises extra power, flexibility, innovation and individuality. The new 20-cylinder light duty version MAN 20V175D-ML"+" meets these requirements and also offers much more! The entire MAN 175D family is in line with the latest technology, is modular and can be tailored to the needs of customers. A technical masterpiece whose clean and contemporary design perfectly matches the lifestyle of its owners. In terms of fuel oil consumption, efficiency and reliability, the 175D is in a class of its own, mastering every performance requirement with aplomb and always keeping the yacht on course.

With power into the future

With the new MAN 175D-ML"+" we are now going one step further! The 20V175D-ML”+" is the most powerful high-speed diesel engine available today – at 2000 rpm it achieves an output of 4400 kW. The first 20V versions of the 175D engine from MAN Energy Solutions are currently being delivered and are expected to set sail in the first quarter of 2022 – these are the medium-duty versions of the 20V175D engine with an output of 3700 kW. The light-duty engine with a record output of 4400 kW will go into production at the end of 2021. It develops its power in an extremely small space and its modern design makes it a visual highlight in the engine room. This power pack has it all: Freedom, relaxation and thrills. Freedom redefined! The MAN 175D-ML"+" can continuously provide maximum power even in tropical conditions. At the same time, this engine also has above-average TBOs (Time Between Overhauls) and the lowest fuel oil consumption in its class.

Green engines

We are already meeting tomorrow's emissions regulations. By using synthetic fuels, the future of a green, CO2-neutral drive can already be realized today. Thanks to sophisticated SCR (selective catalytic reduction) exhaust aftertreatment technologies and the optional integration of batteries for hybrid propulsion and on-board power supply, the MAN 175D is also the right choice in terms of sustainability.
