Volvo Penta D8 Series marine diesel engines use a 7.7-litre, inline six-cylinder platform for motor yachts and sports cruisers. MSS Motorsports lists D8 inboard engines and IPS propulsion packages for vessel repowering, with selection based on hull design, operating load, and installation requirements.

Inboard options include the Volvo Penta D8-550 at 405 kW (550 hp) and D8-600 at 441 kW (600 hp). These are published crankshaft ratings. Match the engine’s duty classification to your vessel’s operating hours and load profile, then confirm gearbox ratio, propeller suitability, and engine-room clearance.

D8 engines combine common-rail fuel injection, twin-entry turbocharging, and charge-air cooling. The cast-iron engine block uses replaceable dry cylinder liners, while freshwater cooling operates through a heat exchanger. Electronic Vessel Control (EVC) integrates engine electronics with compatible controls and instrumentation.

D8-IPS700 and D8-IPS800 packages deliver 550 hp and 600 hp per engine respectively, pairing the engines with steerable pods and forward-facing, counter-rotating propellers. These IPS versions also feature a belt-driven supercharger. Confirm pod specification, EVC generation, and included joystick or other optional functions when comparing packages.

Request a Volvo Penta D8 quotation from MSS Motorsports with your boat details, existing engine identification, and preferred propulsion configuration. Confirm engine condition, gearbox or IPS drive inclusion, control equipment, wiring, and installation accessories. Ask about warranty terms, replacement parts availability, delivery costs, and lead time.
