That's fair question to ask, and we get it a lot.
When a manual has “OEM” in the title, it means it’s officially published or licensed by the original equipment manufacturer — in this case, Volvo Penta. So yes, it’s the real-deal factory manual used by dealers and certified techs.
That said, just because a manual doesn’t include “OEM” in the title doesn’t automatically mean it’s not OEM. Sometimes the designation is simply left out of the title by the publisher or reseller, even if the content is indeed factory-original.
For this particular manual, though, you’re looking at a genuine OEM manual, covering a wide range of Volvo Penta 4-cylinder, V6, and V8 engines. It’s got everything from full engine rebuild procedures to fuel system schematics, ignition diagnostics, stern drive servicing, and more.
So short answer: Yes, this one is OEM — and don’t worry if some others don’t spell it out in the title. Context matters ✌🏻
