New parts and service on Mainship A fuel blockage of gunk caused an engine stop and BoatUS tow from offshore. As I was cleaning the fuel tank I decided to check the coolers and seawater flow. I had noticed when flushing the engine that the water flow was low. Heat Exchanger flues for cooling The aftercooler was clogged. Zinc was almost gone Sea water and calcium deposits.
