Volvo Penta engine models covered
Spare parts RFQs may reference Volvo Penta D6 through D13 marine configurations, TAD industrial series or TWD configurations. Exact model, serial/build and installed application are checked before a route is confirmed.
D6-370
6-cylinder inline marine diesel, 370 hp. Pistons, cylinder liners, injectors, turbocharger components, heat exchanger elements, gasket sets.
D8-510
In-line six-cylinder commercial inboard rated at 510 hp — the 8 in D8 is the displacement class, not the cylinder count. Cylinder heads, valve assemblies, fuel injection pumps, crankshaft bearings, intercooler components, overhaul kits.
D11-670
11-litre 6-cylinder heavy-duty marine diesel, 670 hp. Piston ring sets, liner kits, exhaust valve seats, injection nozzles, cooling water pump assemblies.
D13-800
D13-800 RFQs can include cylinder head gaskets, connecting-rod bearings, fuel-pump plungers, turbocharger cartridges and lube-oil-system parts. Confirm build evidence.
D13-1000
Top-output D13 configuration, 1000 hp. High-performance piston crowns, exhaust valve assemblies, injection equipment, camshaft drive components, complete overhaul kits.
TAD series
TAD1640, TAD1641, TAD1642, TAD1643 and related RFQs can include engine, fuel, cooling and overhaul components. Confirm the complete model suffix, serial/build and installed application.
TWD series
Heavy-duty turbocharged and aftercooled industrial diesel — TWD1240, TWD1643 and variants. Cylinder liners, piston assemblies, heads, injection parts, cooling systems.
The number in a D-series name is litres, not cylinders
A Volvo Penta marine designation is read in two halves, and the first half is misread more often than any other detail on the engine. D4, D6, D8, D11, D13 and D16 name the platform by its approximate displacement in litres. They do not name the cylinder count. A D8 is an in-line six of roughly eight litres, and so are the D11, D13 and D16; only the D4 happens to carry as many cylinders as its badge suggests. An enquiry written on the assumption that a D8 has eight cylinders will describe a head, a liner set or a bearing set in the wrong quantity before anyone has looked at a part number.
The number after the dash is the rated output. D8-450, D8-510 and D8-550 are the same platform at three ratings, and that is not a cosmetic difference: rating changes what is fitted on the fuel and charge-air side, so two engines sharing a platform name can take different components. The rating belongs in the enquiry alongside the platform, which is why D8-510 is a usable line and D8 on its own is not.
The industrial and generating-set designations follow their own logic. A TAD or TWD string carries a numeric block and one or more trailing letters, and engines that differ by a single digit — TAD1640, TAD1641, TAD1642, TAD1643 — are not interchangeable for parts. On those the complete string, every character of it, is the minimum an enquiry can be written from.

Three numbers on the plate, and the drive keeps its own
Volvo Penta puts three separate identifiers on an engine, and they do different jobs. The product designation names the platform and the rating. The product number names the specific build, down to what was fitted at the works. The serial number names the individual engine. A parts route is confirmed against the second and the third, not the first. On an Aquamatic sterndrive or a Forward Drive installation there is a fourth and a fifth: the drive unit and the reverse gear carry their own identification numbers on their own plates, and a line about a drive cannot be answered from the engine plate at all.
- Product designation exactly as written, complete with the rating — D8-510, not D8
- Product number from the same plate, which is what separates one build from another
- Engine serial number, photographed rather than transcribed
- Drive unit identification number and reverse gear number where the line touches the drive or the gear
- Where the number was read from — the plate sits on the block, and many engines repeat it on a decal on the cover
- Installation: inboard shaft line, IPS pod, sterndrive, generating set or industrial duty
- For a generating set, the alternator make and its own plate data, since the alternator is a separate maker
- Model or build year, because option content changes inside a single designation
- Cylinder number the component came off, for any running-gear line
- Old part number and the catalogue page it came from, treated as a starting point rather than a conclusion
- Bearing shells with the undersize stated, and ring sets quoted per cylinder rather than per ring
- Injector, high-pressure pump and common-rail components separated by name, because the three are different orders
- Heat exchanger, charge-air cooler and keel-cooling parts distinguished, since the cooling arrangement varies by installation rather than by platform
- Running hours and any earlier reconditioning of the item itself
- Photographs of the plate, of the cover decal and of the component in place
Volvo Penta supply route review — OEM and verified alternative.
Volvo Penta requests may need OEM-route review, verified alternative review or both depending on urgency, approval requirements, documentation and budget logic. Vessel Core structures the RFQ around the buyer's approval context and vessel timing.
OEM or Alternative — Your Choice
For class-surveyed vessels and warranty-sensitive applications, OEM-route review can be requested. For planned running maintenance, verified alternative components can be reviewed when documentation and specification context permit.
Model-specific RFQ review
D-series, TAD and TWD requests can be reviewed from the complete engine designation, serial/build and installed-duty evidence. Models listed here do not imply stock, compatibility or authorised-dealer status.
Lead Time Confirmed at RFQ Stage
Lead time, availability and freight options are confirmed at RFQ stage based on part specification, approval requirements, vessel ETA and destination port.
Technical Part Identification
No part number? We can start the review from engine serial number, model designation, build year and component photographs, then clarify the missing details before supplier outreach.
Workboat & Offshore Ready
Volvo Penta D and TAD series engines are standard on pilot boats, CTVs, patrol craft, and harbour tugs — vessel types with tight operational schedules and minimal maintenance windows. We coordinate supply around your vessel's operational calendar, not ours.
Time-Critical Priority Review
Propulsion failures and generator set breakdowns on Volvo Penta-powered vessels receive priority RFQ review. Time-critical RFQs are checked against supplier availability, route options, freight options and port timing.
