00:00This 70-year-old marine thruster has spent decades beneath the sea. Thick rust,
00:06barnacles, and saltwater corrosion have completely seized its propeller and damaged its internal
00:12components. But can this massive underwater propulsion system work again? Watch every step
00:19as it's carefully dismantled, deep cleaned, rebuilt with precision, and finally tested in a
00:26powerful underwater thrust demonstration.
