RedactedNarrative: While pulling a tuber in Station Creek in Beaufort County, South Carolina, Unit 1 felt a vibration coming from the engine.  The operator of Unit 1 went to investigate and found water running into the engine compartment from the stern near the outdrive.  Unit 1 was pulled up to the shoreline and passengers got in a separate good Samaritan vessel.  Unit 1 continued to take on water until the stern was under the water line.  Beaufort Marine Search and Rescue was able to tow Unit 1 back to Station Creeklanding where it was put back on the trailer.
