With 230 hp at 3,400 rpm, the Volvo Penta D4-230 uses a turbocharged and aftercooled 3.7L inline four-cylinder diesel configuration with common rail fuel injection. The supplied specifications identify EN 590 or ASTM D975 diesel and a 17.5:1 compression ratio. Hydraulic marine gear, HS63AE or HS85A drive compatibility, SAE 4 flywheel housing, and Electronic Vessel Control define the listed propulsion interfaces.
The 1,217-pound dry engine uses a 12V 150-amp or 24V 80-amp alternator, heat-exchanger cooling with 13L coolant capacity, and a water-cooled manifold exhaust configuration. Pressure-feed wet-sump lubrication holds 9L oil. Listed EPA Tier 3, IMO II, and RCD II ratings, together with the specified 1-3-4-2 firing order, provide technical context.
Why Choose the Volvo Penta D4-230 Marine Diesel Engine
The D4-230 marine diesel engine combines 230 hp at 3,400 rpm with turbocharging, aftercooling, and common rail injection in a 3.7L four-cylinder configuration. Buyers comparing electronic-control propulsion packages can assess its hydraulic marine gear, HS63AE or HS85A drive options, EVC compatibility, and dual-voltage alternator choices. The supplied 1,217-pound dry weight, 13L coolant capacity, and listed emissions ratings support installation planning.
