Yanmar 8LV-320Z – Marine Diesel Engine 320 HP

Yanmar 8LV-320Z 320 HP – Sterndrive Diesel Propulsion System

Integrating high-torque diesel performance with the maneuverability of a sterndrive unit is the mechanical solution provided by the Yanmar 8LV-320Z. Specifically engineered for the ZT370 hydraulic clutch sterndrive, this 320 HP V8 package solves the problem of sluggish throttle response in heavy American sterndrive cruisers. The twin-turbocharged system ensures a flat torque curve, allowing for effortless planing even when the vessel is heavily loaded with fuel and gear for weekend trips.

Adhering to USA EPA Tier 3 standards, the 8LV-320Z combines eco-friendly operation with the rugged durability required for American coastal patrol and recreational use. The inclusion of the ZT370 drive provides exceptionally smooth gear shifting due to its hydraulic clutch design, reducing the “clunk” typically found in mechanical sterndrives. With a 180A alternator and NMEA 2000 compatibility, this engine package is designed for the high-tech demands of modern USA marine navigation systems.
