Yanmar 3JH3E heat exchanger flush and leak repair, can it be saved? | Ep.15

While servicing the starboard engine we find out the coolant is just completely black... On thing turns into another and we are taking off the whole heat exchanger on this Yanmar engine to clean it up. 20+ years of neglect have not done this heat exchanger well and the O rings were just completely gone. This has led to salt water mixing with the coolant and corroding the engine block causing the coolant to turn completely black and filled with rust particles. After many flushes, cleaning and more flushes we get back to a usable system again. Want to help us out?
