YANMAR introduces the 6LF common rail engine series
YANMAR engines are famous for having always set the global standards in propulsion for sailing boats and small craft. It is now also recognised that our engines are the top-tier solution on the market, offering responsive power, excellent fuel efficiency and unrivalled reliability. With a customisable range of options, YANMAR engines are proving to be the ideal solution for powerboat applications.
Following the successful completion of a lengthy evaluation period, YANMAR Marine International is pleased to announce the official introduction of the YANMAR 6LF common rail engine series.
The new 6LF series offers a range of three engine ratings, with outputs of 485, 530 and 550 mhp, placing the new engines immediately above our 6LY-CR series in terms of mhp.
After the engine’s preview to the public at the Düsseldorf show and the Miami International Boat Show in early 2020, we had to face delays due to COVID-19. We are now happy to announce that the 6LF series can be ordered.

General features of the 6LF series
To expand our marine engine line-up, YANMAR took its cue from customer requests to find the best possible solutions and specifications – high power, low weight and compact installation. Controlled by Bosch common rail technology, the 6LF exceeds EPA TIER 3 and EU RCD 2 emissions standards. The 6LF has low noise and vibration levels and low exhaust emissions, is designed for easy usability and is compatible with a wide range of fuel types such as EN15940, JP5 and JP8.

Meeting the needs of a wide range of applications in recreational boating, the 6LF is the perfect solution for:
- Superyacht tenders
- Planing and semi-planing motor yachts up to 17 m
- High-performance light commercial vessels
