Make sure the bilge is free of any debris or oil that might clog the pump or interfere with the switch, and that the bilge pump is wired directly to the batteries so that it will operate when all of the switches are turned off at the main panel. Also check the operation of bilge pumps. After you’ve cleaned the bilge, add enough nontoxic antifreeze to trigger the float switch. Bail or sponge the remainder out. Repairing freeze damage takes time and all too often involves a complete engine replacement. By the time the boat is in working order, a good part of the boating season will have been lost. Winterizing most boats takes from an hour to a day. Unless you are located in Hawaii or the Florida Keys, we recommend winterizing your engine if you will be laying up the boat for even a few weeks to minimize the chances that a sudden freeze will put it out of commission next season. We initially measure the area to be wrapped. The shrink wrap will need to cover the entire top of the boat, including extra height for windshields and other protrusions down to an area on the hull below the rub rail. After we determine the measurements for your boat, our shrink wrap manufacturer purchase the amount of wrap you need and a heat gun if necessary.
