Yanmar
8LV320
The complete line-up of YANMAR’s new-generation common rail marine diesel engines suits a wide variety of vessels from sailboats, multihulls, superyacht tenders and motorboats to fast sports craft and wake boats.
Overview
YANMAR’s 8LV is a compact power plant with an extremely efficient and versatile design. The V8 common rail configuration allows for a balanced and quiet running engine with twin turbos to deliver faster acceleration response.
Featuring a broad speed range from 550 rpm idle to 3800 rpm max speed, the 8LV can be applied to fit many, differing application needs from low speed, easy maneuvering to high speed, responsive cruising. And with a large 180 amp alternator as standard, you can efficiently power added features, and do so easily with direct connectivity to all NMEA devices in this electrically controlled engine.
The best power-to-weight ratio in its class and compact size makes this engine ideal, whether for new builds or repowers alike.
