New Yanmar 8LV320 (Z) 320HP Inboard Diesel Engine

New Yanmar 8LV320 (Z) 320HP Inboard Diesel Engine

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.
