8LV 320/370 marine diesel engine from Yanmar Marine. Earlier this year Yanmar known for its high-revving lightweight engines, unveiled its twin turbocharged V-8 diesel in two ” Tier 111 ” compliant models, the 8LV320 and 8LV370 the next-generation, electronic successor to its long-running 315-hp 6LPA-STP2 mechanical diesel. The Yanmar engine coupled with stern drives, it can be used for everything from ski boats to cruisers
With twin turbochargers and direct fuel injection, this new V-8 meets EPA Tier 3 emissions standards, while providing quiet, clean power with only a 93-pound increase in weight. The 8LV can be programmed to put out either 320 or 370 hp, and fits into virtually any engine space formerly occupied by a 315 or another brand of 6-cylinder engine of comparable horsepower.
The 8LV engine for stern drive applications is packaged with the ZT370 twin-prop drive. Yanmar stays true to its low-weight, high-output tradition with the engine, which weighs 450 kilograms and revs up to 3800 rpm, producing up to 370 metric horsepower.
The engine uses Yanmar’s CAN-bus control system for plug-and-play-type installations, making it a great candidate for repower projects.
