Two numbers you need
- Product designation – the model, for example MD2030 or AQ145.
- Serial number – unique to your specific engine.
Volvo Penta uses the model designation and serial number instead of a model year. The same model can have different parts depending on the serial number.
Where are they located?
According to Volvo Penta, the serial number is found on decals and/or plates on the product. Appearance and location vary between models and years of manufacture.
- Look for an ID plate or decal on the engine block, valve cover or intake manifold.
- Drives and reverse gears often have their own plate with a separate number.
- Clean the plate carefully – it may be painted over or dirty.
- Also check the owner's manual, service receipts and purchase documents.
Why it matters
- The right owner's manual and workshop manual.
- The right spare parts, such as impellers, oil and fuel filters, belts and anodes.
- Checking for recalls and service campaigns – Volvo Penta lets you search for these for your product.
- Safer boat buying: the number should match the paperwork.
- An accurate quote from the workshop, since labour and parts depend on the exact engine variant.
Save the number right away
- Photograph the ID plate and decals once you've found them.
- Write down the product designation and serial number for the engine, drive or reverse gear separately.
- Save the photos on your phone and keep a copy at home.
- Bring the numbers when you buy parts, book a service or ask for a quote.
Over the years the plate can become illegible from dirt, paint or corrosion. With the number saved, you won't have to search a cramped engine compartment next time.
Common mistakes
- Reading the plate on the drive or gearbox and thinking it's the engine number.
- Going by a model year – Volvo Penta identifies engines by product designation and serial number.
- Trusting the model name in the listing. Always check the plate yourself, especially when buying a used boat.
- Ordering parts by model name without the serial number, when parts can differ within the same model.
Can't find a number?
Take photos of the engine and the plate and contact a Volvo Penta dealer. They can often identify the engine.
