Volvo Penta D11-625 – Inboard Diesel Engine 625 HP

Managing a 24V charging configuration and a 60L heat-exchanger cooling system, the Volvo Penta D11-625 uses a 10.8L inline six-cylinder diesel platform rated at 625 hp and 2,400 rpm. Electronic unit injectors, twin-entry turbocharging, and aftercooling form the documented engine architecture. Its ZF 325-1A shaft-drive interface, SAE 1 flywheel housing, hydraulic marine gear, and 2,491-pound dry weight require complete propulsion-package planning before installation.

The engine uses EN 590 or ASTM D975 diesel, a stated 16.5:1 compression ratio, and pressure-feed wet-sump lubrication holding 33L oil. A water-cooled elbow forms the specified exhaust arrangement. The supplied specification lists EPA Tier 3, IMO II, and RCD II emissions ratings, while Electronic Vessel Control is identified for the propulsion-system control configuration.
