Yanmar 8LV320 320 HP – Compact Luxury Yacht Diesel V8

Reducing the footprint of high-performance V8 diesels without compromising on torque is the mechanical achievement of the Yanmar 8LV320. Delivering 320 HP at 3800 RPM, this engine provides the refined, quiet operation demanded by the USA luxury yacht market. The twin-turbocharged configuration is specifically tuned for American express cruisers, providing the low-end punch needed for quick acceleration and the high-end efficiency required for long-distance cruising across the Great Lakes or the Gulf Stream.

Adhering to USA EPA Tier 3 regulations, the 8LV320 employs a high-pressure common-rail injection system and an advanced ECU to ensure optimal combustion at all throttle positions. For the American owner, this results in significant fuel savings and reduced environmental impact without sacrificing performance. The engine’s high-capacity 180-amp alternator is designed to keep house battery banks fully charged, supporting the extensive array of AC, refrigeration, and electronics common on modern US vessels.
