Volvo Penta D6-435 – Marine Diesel Engine 435 HP

Description

With a verified 5.5-liter inline 6-cylinder engine block and supercharged turbocharging, the Volvo Penta D6-435 delivers commercial-grade diesel power. Producing 435 horsepower at 3500 RPM, this motor drives fast planing cruisers, charter boats, and sportfishers. The combination of a mechanical supercharger for instant low-end boost and a turbocharger for top-end power eliminates lag when getting heavy hulls onto plane.

Closed freshwater cooling keeps saltwater away from internal engine passages, maintaining peak thermal efficiency. Built with an SAE 3 flywheel housing, the engine features a 115-amp alternator, Electronic Vessel Control network monitoring, and a dry weight of 594 kg.
