What this video covers
A routine oil change on a 1996 37-ft Hunter reveals severe aluminum corrosion on the exhaust manifold of the Yanmar 3J-H2E engine.1:30 The damage, caused by saltwater sitting in the heat exchanger due to a lack of freshwater flushing, prevents the vessel from leaving Green Turtle Cay.2:01 Because the engine model is discontinued and replacement parts are unavailable locally, the crew performs a field repair.3:19 They wire-brush the corroded mating surfaces to reach clean metal, apply Cold Cure Slow Set Steel JB Weld to rebuild the recessed areas, and seal the assembly with RTV gasket maker.3:47 After allowing the epoxy to cure, they reinstall the manifold and successfully restart the engine.9:45 The repair serves as a temporary fix until a replacement part can be sourced.8:49
