Rebuilding Yanmar Diesel from Sunk Boat

We take a step back in time to finish the engine rebuild series, where I finish rebuilding the head and top end of my Yanmar 3Y30 diesel engine from my hurricane damaged Antares 44 catamaran that was damaged by Hurricane Dorian in the Bahamas.
It's a small makeover on the engine as I show you the process I go through to get the engine running again. It's always nice to know there is hope for an engine if your sailboat sinks.
