RedactedNarrative: Vessel got underway from Sheboygan Harbor Centre Marina with intent to travel to lighthouse and back. Winds were a steady 25 knots from the south and had been blowing for several hours with water coming over south breakwall and significant swell entering outer harbor. Owner was at helm. At approximately 5:35pm the vessel lost power in the outer harbor. The engine was running but there was no propulsion. Owner stated he had lost his transmission and was unable to move the shift lever. Vessel drifted northward to where the vessel's port side contacted the north breakwall approximately halfway between inner harbor and lighthouse. Vessel pounded into the breakwall for approximately 20 minutes. All three occupants egressed vessel by climbing onto breakwall. Onlookers on shore called 911 at 5:49m, and the Coast Guard was dispatched to scene. Meverden arrived at Marina at approx. 6:30pm, as Coast Guard was hip-towing vessel to fuel dock. Vessel was taking on water along port side chine. Meverden assisted with damage control, and getting boat onto trailer at Harbor Centre Launch ramp. 
  
  When vessel was pulled from water the Volvo-Penta outdrive was broken from the transom and was hanging by the shift cable. There was no sign of impact damage on the outdrive. Given the outdrive condition and operator statement that the shift lever would not be moved following power loss it is probable that the outdrive separated from the transom due to corrosion, heave sea state, and / or striking submerged object and caused the power loss. 
  
  Following power loss, none of the boat's occupants attempted to deploy the vessel's anchor, located in a wood pulpit at the bow. The anchor was a lightweight Danforth type, with nylon anchor rode attached directly to the anchor without chain. Given the vessel size and sea conditions, the anchor would have been ineffective if deployed.
