This video is a detailed demonstration of the fresh water cooling system of a salt water Yanmar diesel marine engine, including a description of repair principles and anticorrosion features to control galvanic reactions. The engine shown is a Yanmar 3GMFC engine with the SB20 sail drive. I show details of how to drain and refill/replace the antifreeze/coolant, and describe the layout of engine zincs present in some models.
This is an amateur presentation offered for free and in good faith, but with no guarantees as to accuracy or safety. Engine repair comes with inherent risks. Any misadventure you encounter if you decide to accept the risk of DIY repair is your responsibility.
