Volvo Penta D6-480 – Inboard Diesel Engine 480 HP

Volvo Penta D6-480 480 HP – Precision Performance Marine Diesel

Overcoming the lag associated with high-horsepower diesel engines, the Volvo Penta D6-480 delivers 480 HP at 3700 RPM through a sophisticated supercharger and turbocharger combination. This dual-charging system provides the instantaneous low-end punch needed for fast-planing American sportfishers and express cruisers. The 5.5-liter, 6-cylinder architecture is built with a cast-iron block and ladder frame to ensure mechanical longevity under the high-stress conditions often encountered during offshore fishing tournaments in US coastal waters.

Adhering to strict USA EPA Tier 3 emission mandates, the D6-480 utilizes common-rail technology and an advanced ECU to ensure a clean-burning transom and optimized fuel economy. For the American operator, the integrated EVC system allows for advanced features like Dynamic Positioning and autopilot integration, simplifying complex maneuvers in crowded USA marinas. Its robust freshwater cooling system is engineered to prevent corrosion in high-salinity environments, ensuring consistent performance in the Atlantic, Pacific, and Gulf coasts.
