At the SMM Hamburg, French engine manufacturer Moteurs Baudouin unveiled the 6F21. This new 6-cylinder, 12.5-liter engine produces up to 735 kW/1000 HP, enabling a best-in-class power density in a very compact and light original marine design.

This level of performance was achieved through continuous technological evolution. The 6F21 includes a strengthened engine structure to withstand high torque and a higher cylinder pressure well over 200 bar. A two-stage turbocharger system is also fitted on the engine, along with two intercoolers, and a high-end common rail system, operating at 2200 bar. All of these competitive advantages are contained in the most compact engine ever released from Baudouin.

We wanted to make an engine that is versatile for both the commercial and pleasure markets” says Claudio Operti, Chief Engineer at Baudouin. “This engine needed to be as compact as possible without compromising power, while at the same time keeping true to Baudouin’s DNA of offering robust and truly marine engines.”

Baudouin 6F21: reliability and robustness

The result is a high-power and light engine, but one that still promises a long life, with the reliability and robustness that Baudouin are known for. Every 6F21 engine also has optimized maintenance for low total cost of ownership, and complies with IMO II and EPA III standards, with IMO III and EPA IV following soon.

The 6F21 is available in three duty ratings with continuous compact power. This includes best-in-class for power output at intermittent duty 599 kW/815 HP and light duty 662 kW/900 HP, and co-leader at the high-performance rating delivering 735 kW/1000 HP. While overall, the engine is best-in-class for power density throughout all three duty ratings.

This power range ensures adaptability across a wide spectrum of light duty applications like military, recreational and pilot boats, and releasing in the coming months, commercial ratings for heavy duty applications such as fishing, firefighting, and passenger boats.

Steven Wang, CEO at Baudouin, says: “The 6F21 is the first step toward a new series of engines offering the best power in the market, and consolidating Baudouin as a trusted solution both for the commercial and pleasure market. For larger applications, we are also preparing to expand the burgeoning F series with an 8-cylinder 17L version of the engine, coming later in 2022.”
