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.

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 worldwide Yanmar support, wherever, whenever.
