Description
Volvo Penta D6-380 380 HP – Advanced Common Rail Inboard
Optimizing fuel mapping for sustained mid-range cruising is the primary mechanical focus of the Volvo Penta D6-380. Delivering 380 HP at 3500 RPM, this 5.5-liter, 6-cylinder engine utilizes a high-pressure common-rail system and a wastegate turbocharger to provide a balanced and efficient power curve for American recreational boaters. The robust cast-iron cylinder block and ladder frame ensure long-term durability, making it a premier choice for USA yacht owners who demand reliability during extended coastal transits from the Northeast to the Florida Keys.
Meeting all USA EPA Tier 3 emission standards, the D6-380 integrates Volvo Penta’s EVC (Electronic Vessel Control) for ultra-smooth shifting and precise throttle management. For the American operator, this engine package supports full NMEA 2000 connectivity, allowing real-time engine health data to be displayed on Garmin or Raymarine helm suites. Its freshwater cooling system is designed with high-capacity heat exchangers to maintain stable operating temperatures even in the warm, high-salinity waters of the Gulf of Mexico.
