LAKE OF THE OZARKS, Mo. — Boaters and marinas are in the busy winterizing season at the Lake. And while most boaters are probably safest to hire experts to do the work, BoatUS has a winterizing brochure and checklist for DIY'ers or boat owners who just want to make sure they're getting what they paid for.

Winterization is key, since water that is mistakenly left in a boat’s engine block to freeze over the winter is sure to become an expensive repair bill come springtime. As the ice expands, it can crack the block and ruin the motor, damage fiberglass, split hoses, or destroy a boat’s refrigeration system. 

The online brochure addresses the reasons for more than 95 percent of the freeze claims handled by the BoatUS Marine Insurance Program. Included are sections on boat storage, engines and outdrives dos and don’ts, winterization contracts, green winterizing, as well as preparing boat plumbing. A winterization checklist is also included.
