Yanmar 8LV350 – Inboard Diesel Engine 350 HP

Yanmar 8LV350 350 HP – High-Efficiency V8 Marine Propulsion

Solving the vibration and weight issues common in high-horsepower diesel setups, the Yanmar 8LV350 utilizes a 90-degree V8 architecture to provide smooth, balanced power delivery. Generating 350 HP at 3800 RPM, this twin-turbocharged engine is optimized for high-speed planing hulls, offering a superior power-to-weight ratio that enhances fuel economy for American sportfishers. The wide power band ensures rapid throttle response, allowing US captains to navigate tight inlets and heavy seas with absolute confidence.

Meeting EPA Tier 3 emission standards, the 8LV350 features a sophisticated common-rail fuel system that provides clean, odor-free operation even at low idle speeds. This model is designed for seamless integration with the Yanmar VCS (Vessel Control System), providing modern American boaters with intuitive fly-by-wire controls and high-capacity electrical output for advanced navigation suites. Its robust freshwater cooling system is engineered to prevent galvanic corrosion in high-salinity Atlantic and Pacific waters.
