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

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.

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.

 YANMAR 8LV – Power, Precision & Performance Redefined From ski boats to fast sports craft and luxury cruisers—whether for new builds or repowering projects—the Yanmar 8LV stands at the forefront of modern propulsion technology. It delivers the high-end performance typically associated with V8 gasoline engines, combined with the durability, efficiency, and long-life benefits of diesel.

Unmatched Performance

• The V8 8LV engine can be perfectly paired with Yanmar’s twin-propeller sterndrive (ZT370) or the KMH50 inboard transmission, ensuring smooth and responsive propulsion.

• Designed for maximum performance with minimum weight, this big displacement engine weighs just 435 kg (dry), setting a new benchmark for power-to-weight ratio.

• Offers an impressive power band, with idle speeds as low as 550 rpm, ideal for precise low-speed maneuvering in marinas—further enhanced by the hydraulic clutch of the ZT370 or KMH50 systems.

• Delivers a maximum engine speed of 3,800 rpm, leading the segment for acceleration and top-end performance.

Efficiency Meets Endurance

• High power and torque output combined with low noise and vibration, ensuring a smooth and quiet ride.

• Exceptional fuel efficiency, allowing you to go farther on every tank.

• Equipped with a 12V, 180A alternator, providing ample power for all onboard electrical systems and accessories.

Smart Control & Easy Integration

• Incorporates Yanmar’s advanced CAN-bus control system (Yanmar VCS) for reliable, integrated engine management—no third-party systems required.

• Designed for easy installation and simple servicing, reducing downtime and maintenance costs.

• Supported by Yanmar’s global service network, ensuring expert assistance wherever and whenever you need it.

Experience the 8LV Advantage

With its perfect balance of strength, sophistication, and smart engineering, the Yanmar 8LV delivers:

• The thrill of V8 performance

• The efficiency of modern diesel power

• The confidence of global Yanmar reliability

For ski boats to fast sports craft to luxury cruisers – new build or repowering – the 8LV is at the forefront of today’s propulsion technology, providing the kind of high end performance associated with V8 gasolene engines, but with all of the solid, long-life and cost-effective benefi ts of diesel. This V8 can be matched perfectly with Yanmar’s latest twin-propeller sterndrive, the ZT370, or to a KMH50 inboard transmission. Yanmar remains dedicated to achieving maximum performance from minimum weight and the 8LV proves the point: another big displacement engine, weighing in dry at a mere 435 kilograms. The 8LV provides boaters with the best-in-class power band. It idles at 550 rpm, capable of crawling speed in the marina, aided further by the hydraulic clutch of the ZT370 or KMH50 drive systems. Maximum engine speed is a big 3,800 rpm – well ahead of other engines in this segment. You can enjoy high power, high torque. Low noise, low vibration. You can go much further on a tank of fuel. There is the advantage of a 12 volt, 180 amp alternator to charge all your onboard electrics. The 8LV uses Yanmar’s new CAN-bus control system, the Yanmar VCS, so you don’t have to rely on anyone else. Then there is easy installation, simple servicing, and all that worlwide Yanmar support, wherever, whenever.
