RedactedNarrative: V1 left Stump Pass Marina at approximately 10:30. While on a plane approximately 10 minutes V1 ran aground.  V1 didn’t hit bottom hard enough to throw anyone to the deck or overboard.  The vessel was able to get into deeper water by its own power (no one got in the water to push it free).  V1 continued South in the ICW to Don Pedro Island dock.  V1 remained at the dock for approximately 2 hours, then at approximately 13:30 got under way to return to Stump Pass Marina.  Approximately 30 minutes after leaving the Don Pedro dock, while North bound in the ICW, in the Cape Haze area V1 lost power.  Upon inspection of the 90 horse power engine, the lower unit had sheared off.
