YANMAR powerboat engines deliver outstanding power, speed, efficiency, and reliability. Our engines have proven to be the ideal solution for multiple applications, commercial and recreational, given a customizable options range - available for shaft, stern, and jet drives, with SOLAS and semi 2-pole option, high power primary and secondary alternators, purpose-built plug & play interconnectivity to any NMEA or J1939 device, and more. YANMAR engines deliver 5x Best in Class product features with the added benefit of the best global support network in the marine industry.
Combining the latest engine technologies, including new generation common-rail systems and the most advanced, complete combustion in YANMAR’s line, the 4LV Series is undoubtedly cleaner, quieter, and produces more torque & acceleration than any other engine in its class.
The 4LV proves to be an extremely efficient engine without any compromise on quality. Featuring Thermo Swing Wall Insulation Technology and incorporating 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.
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.
