Changing Oil on Our Yanmar 4JH4E (If We Can Do It, Anyone Can!)

We’re not mechanics — just two sailors trying to keep our boat running! In this video, we take on the challenge of changing the oil and impeller on our Yanmar 4JH4E engine for the first time. The video is long and slow because we wanted to show the real process — from our clumsy moments to small victories (yes, even tightening a screw took effort 😅). If you’ve ever thought, “I could never service my own engine,” this video is for you. You totally can — and we hope this gives you the confidence to try! ⚓ What we cover: Full oil change on Yanmar 4JH4E Changing the impeller Tools we used Mistakes we made & what we learned 🎥 Boat: Najad 380 Indara 👩‍🔧 Engine: Yanmar 4JH4E ⛵ Subscribe for more sailing life, maintenance adventures, and honest moments aboard Indara! #Yanmar4JH4E #DIYBoatMaintenance #SailingLife #Najad380 #BoatEngineService #CruisingCouple
