Volvo Penta D6-340 – Inboard Diesel Engine 340 HP

Description

With 340 hp at 3,400 rpm, the Volvo Penta D6-340 uses a turbocharged and aftercooled 5.5L inline six-cylinder diesel configuration with common rail fuel injection. The supplied specifications identify EN 590 or ASTM D975 diesel, a 17.5:1 compression ratio, and hydraulic marine gear. EVC controls, an SAE 4 flywheel housing, and HS85A or ZF-compatible drive arrangements define the listed propulsion interfaces.

The engine is supplied with a stated 690 kg dry weight, 12V 150-amp or 24V 80-amp alternator options, and heat-exchanger cooling holding 16L coolant. A water-cooled manifold forms part of the exhaust system, while wet-sump pressure-feed lubrication uses 20L oil capacity. Listed emissions ratings include EPA Tier 3, IMO II, and RCD II.

Key Specifications of the Volvo Penta D6-340 Marine Diesel Engine

• The 5.5L inline six-cylinder engine produces 340 hp at 3,400 rpm through turbocharged and aftercooled common rail diesel operation.
• Common rail injection supports the supplied EN 590 or ASTM D975 fuel requirement with a stated 17.5:1 compression ratio.
• HS85A or ZF-compatible drive arrangements require drivetrain confirmation alongside the hydraulic marine gear and SAE 4 housing.
• EVC electronic controls require compatibility planning between the engine, helm controls, propulsion package, and vessel electrical system.
• Alternator options include 12V 150-amp or 24V 80-amp outputs for the listed electrical-system configurations.
• Heat-exchanger cooling holds 16L coolant, while the water-cooled manifold defines the specified exhaust-system arrangement.
• Wet-sump pressure-feed lubrication uses 20L oil capacity, requiring service access for scheduled maintenance and fluid inspection.

Engine Configuration and Service Access

This Volvo Penta marine diesel engine uses 103 by 110 mm bore and stroke dimensions in an inline six-cylinder, four-stroke layout. The turbocharger, aftercooler, common rail fuel system, water-cooled manifold, heat exchanger, alternator, and hydraulic marine gear should remain accessible after installation.

The supplied 690 kg dry weight should be verified against the final propulsion package and installation documentation before engine-bed design. Final routing for electrical wiring, cooling-water plumbing, exhaust, controls, and shaft components should allow inspection and maintenance access.

Why Choose the Volvo Penta D6-340 Marine Diesel Engine

The D6-340 marine diesel engine combines 340 hp at 3,400 rpm with turbocharging, aftercooling, and common rail injection in a 5.5L six-cylinder layout. Buyers can assess its EVC controls, hydraulic marine gear, HS85A or ZF-compatible drive options, and dual-voltage alternator choices. The supplied 16L coolant capacity, 20L oil capacity, and listed emissions ratings provide further installation data.

Installation and Compatibility Considerations

Confirm engine-bed capacity against the supplied 690 kg dry weight and verify the final propulsion package, SAE 4 flywheel housing, hydraulic marine gear, HS85A or ZF-compatible drive arrangement, and EVC control configuration. Plan shaft alignment, propeller matching, fuel supply, cooling-water intake, water-cooled manifold routing, alternator voltage, ventilation, and access around forced-induction components before installation.

Use fuel meeting EN 590 or ASTM D975 requirements. Confirm provisions for 16L coolant capacity, 20L wet-sump oil capacity, hydraulic gear servicing, and access to the common rail system, turbocharger, aftercooler, cooling system, exhaust manifold, and electrical components.

Warranty and Support

Warranty coverage should be confirmed against the current Volvo Penta warranty policy applicable to the exact engine, purchase market, installation, and operating use.
