Volvo Penta D6 Series marine diesel engines use a 5.5-litre, inline six-cylinder design for cruising boats and motor yachts. MSS Motorsports lists shaft-drive inboards, Aquamatic sterndrive packages, IPS systems, and selected waterjet engines for marine engine replacement and boat repowering.
Inboard options include D6-300I, D6-340I, D6-380I, D6-440I, and Volvo Penta D6-480I models, covering 300–480 hp at the crankshaft. Listed Aquamatic DPI packages span 300–440 hp, including the D6-440A DPI. Earlier D6-330, D6-370, and D6-435 models also appear, so confirm the generation before selecting a replacement.
D6 engines combine common-rail fuel injection, double overhead camshafts, turbocharging, and charge-air cooling. Freshwater cooling through a heat exchanger regulates engine temperature, while Electronic Vessel Control (EVC) integrates electronic throttle, shifting, and engine monitoring. Match retained controls, displays, and wiring to the supplied EVC system.
Compare propulsion packages by duty rating, transmission ratio, installation dimensions, and propeller requirements. IPS450 and IPS500 identify propulsion systems; verify the actual horsepower per engine and the matching pod specification. For waterjet repowers, check that engine output and operating speed suit the jet unit and driveline.
Contact MSS Motorsports with your vessel details, existing engine serial number, and required configuration for a Volvo Penta D6 quotation. Confirm engine condition, included transmission or drive, EVC equipment, and installation accessories. Request applicable warranty terms, replacement parts availability, delivery costs, and lead time.
