What Happened
MAN Engines has introduced the MAN i6X, a new inline-six cylinder marine engine delivering 1,000 hp (735 kW) from 12.4 liters of displacement. The engine is designed for yachts and sportfishing boats, offering a novel single-turbocharging concept that reduces complexity and weight while maintaining high power density. It is the next development stage of the proven D26 platform, first introduced in 2015 for workboats and later as the MAN i6 for yachts.
“With the MAN i6X, we are advancing our proven inline-six platform into higher power ranges. The new charging concept creates clear advantages in the drivetrain that were not available in this form before.”
3,250 NmNm
Available swiftly for agile acceleration, especially at low rpm.
- 1,000 PS (735 kW)
- 900 PS (662 kW)
- 730, 800, and 850 PS (537, 588, 625 kW)
- Novel single-turbocharging concept for high power density
- Power-to-weight ratio of 0.8 PS/kg (~0.6 kW/kg)
- Compact dimensions nearly identical to MAN i6; same customer interfaces
- Meets IMO Tier II, EPA Tier III, and EU Sportboat Directive 2013/53EU

Why this matters
The new engine offers higher power and better dynamics in a compact package, giving yacht builders more design flexibility. Its single-turbo approach reduces complexity and weight while improving responsiveness, benefiting boaters needing quick acceleration and maneuvering. It also meets IMO Tier II, EPA Tier III, and EU Sportboat Directive standards for global markets.
