4LV series 150 - 170 - 195 - 230 - 250 MHP 

Featuring the latest engine technologies, the 4LV Series is undoubtedly cleaner, quieter, and produces more torque and acceleration than any other engine in its class. 4LV is the ideal solution for super yacht tenders, small motorboats, light duty commercial vessels, and sailing yachts over 50 ft.


  • Specifically designed for super yacht tenders, small motor boats, light duty commercial vessels, and sailing yachts over 50 ft.
  • Powerful low-end torque performance, delivering superior acceleration
  • Exceeds EPA Tier 3 and RCD Stage 2 emissions regulations
  • Measures significantly low in smoke, odor, and noise
  • Direct connectivity for plug and play integration

Clean & Quiet
The 4LV proves to be an extremely efficient engine without any compromise on quality. Featuring the newest system in common-rail technology, the mid-range engines deliver maximum performance and reliability, while maintaining minimal fuel consumption and exceptionally low noise & emission levels. By exceeding the strict EPA Tier 3 and EU RCD Stage 2 emission regulations, the engines feature virtually smoke and odor free operation.

Performance & Acceleration
Equally, the 4LV doesn’t disappoint in performance. The 2.8 L displacement delivers a powerful low-end torque performance. This results in a stunning acceleration and really sets these engines apart from others in their power range.

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. Fulfilling needs across all boating applications, the 4LV 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 will be complemented by a choice of YANMAR’s expanding controls, including the VC10 electronic control panel, providing real time diagnostics, and the JC20 joystick system, providing innovative maneuvering solutions.
