RedactedNarrative: Vessel was traveling north along the East shoreline when the operator reported seeing an orange life jacket floating on the water. Operator stated he believed the life jacket had been lost off another boat and did not think much of it. The vessel continued northward when operator reported feeling a sharp thud as his vessel passed over a floating 10" hard sump line. As the vessel passed over the pipe, the outdrive was ripped free of the transom and sank. The vessel had to be brought to shore and beached due to intake of water and damages to the outdrive. The missing outdrive was recovered in six feet of water. Three orange life jackets were the only visual marker indicating an obstruction of any kind. Vessel was towed to North Beach State Park boat ramp.
