Yanmar vs Perkins vs Cummins: Which Marine Diesel Actually Lasts

Cummins, Perkins, or Yanmar? Thirty five years of surveys says the badge on the valve cover isn't what decides it. It's whether that block has a replaceable liner or a parent bore, and whether the last owner actually serviced the aftercooler and exhaust elbow. This one breaks down all three brands model by model, what really kills each engine before the block ever does, and the five minute checklist to run before you sign anything. ⚓ Not investment advice. Always get an independent marine survey before buying any boat. #MarineDiesel #Cummins #Perkins #Yanmar #TrawlerLife #BoatBuying #LiveaboardLife #MarineSurvey #Cruising #DieselEngine
