Volvo Penta D4-260 – Marine Diesel Engine 260 HP

Volvo Penta D4-260 260 HP – High-Torque Performance Inboard

Managing thermal loads during sustained high-speed cruising is the primary mechanical challenge addressed by the Volvo Penta D4-260. This 3.7-liter, 4-cylinder engine is engineered with a robust cast-iron block and a ladder frame to ensure structural integrity under the high combustion pressures required to deliver 260 HP at 3500 RPM. For American boaters, this translates to a reliable power plant that provides the necessary punch for getting heavy-displacement hulls on plane quickly, even in choppy USA coastal conditions.

Adhering to strict EPA Tier 3 emission standards, the D4-260 utilizes advanced common-rail fuel injection and double overhead camshafts to optimize fuel efficiency and minimize noise levels. This engine is fully integrated with Volvo Penta’s EVC system, allowing for precise digital control and easy integration with NMEA 2000 marine electronics favored by USA yacht owners. The high-efficiency heat exchanger system is specifically designed to resist internal scaling in high-salinity waters, ensuring consistent cooling performance during long-distance transits.
