YANMAR’s 4LV Series proves to be an efficient engine without the need to compromise on quality. Featuring the latest innovations in common rail technology, these mid-range engines deliver maximum performance and reliability, while delivering minimal fuel consumption, and exceptionally low noise and emission levels.

By exceeding the strict EPA Tier 3 and EU RCD Stage 2 emissions regulations, the engines feature a virtually smoke- and odor-free operation.

Equally, the YANMAR 4LV Series doesn’t disappoint in performance. The 2.8L displacement delivers powerful low-end torque. This results in stunning acceleration, which elevates it over the competition.

To ensure support of advancing marine technologies, direct connectivity to NMEA and J1939 CAN-bus networks has been purpose engineered into the 4LV range, allowing future-proofed integration to any multifunction bridge display.

Over and above the impressive performance, the resounding benefit of the 4LV Series remains its versatility, with all models available with multiple shaft drive options and the durable YANMAR ZT370 sterndrive. Fulfilling needs across all boating applications, it is the perfect solution for new builds and repowering.

It is compact and easily fits into previous model footprints. An ideal installation for sailboats, motor boats, or light commercial vessels, the 4LV range is also complemented by a choice of YANMAR controls. These include the VC10 electronic control system, providing real-time diagnostics, and both the JC10 sterndrive joystick system and the JC20 shaft drive joystick system, providing innovative maneuvering solutions.

*Please note, the 4LV250 is not EPA Commercial certified.
