Volvo Penta D4 Series marine diesel engines use a 3.7-litre, inline four-cylinder platform developed for marine propulsion. MSS Motorsports lists shaft-drive inboards, Aquamatic sterndrive engines, and D4-based IPS packages for cruising boats, motor yachts, and marine repower projects.
Options include the Volvo Penta D4-175I at 175 hp, D4-230I, D4-270I, D4-300I, and D4-320I. Aquamatic DPI listings span 150–320 hp, including the D4-320A DPI. Earlier D4-180, D4-225, and D4-260 models also appear in the catalog, so identify the exact engine generation when comparing specifications.
Common-rail fuel injection, turbocharging, charge-air cooling, and freshwater cooling are core D4 features. Electronic Vessel Control (EVC) connects the engine with compatible throttle, shift, and helm electronics. D4-270/300/320 DPI versions also use a supercharger; equipment and control compatibility vary by generation and package.
For a repower, match the gearbox or drive, reduction ratio, engine mounts, and propellers. Sterndrive installations also require transom-shield compatibility. IPS350 and IPS400 are propulsion system names; confirm the actual horsepower per engine and complete pod specification when comparing IPS packages. Select the appropriate duty rating for the vessel’s intended use.
Request a Volvo Penta D4 engine quotation from MSS Motorsports with your vessel details, existing engine serial number, and preferred propulsion configuration. Confirm engine condition, included gearbox or drive, EVC controls, wiring, and installation components, together with warranty terms, parts availability, lead time, and delivery costs.
