Most sit-on-top kayaks have a drain plug in the bow or stern. Many sit-inside kayaks have them too. A lost drain plug must be replaced in order for the kayak to safe again. Replacement screw-in drain plugs come in two basic types, those with coarse squared threads, and those with fine pointed threads. If you can match the thread type the drain plug will screw right into the boat, regardless of brand. If you are looking to replace a plug that screwed into an oval base, be sure to get a plug with a base to be 100% sure of fit. (Removal and replacement of the base is easy! See the How To Install A Drain Plug Video.) Some kayaks, particularly older Ocean Kayaks may have had a rubber stopper. Any kayak can have a drain new plug installed to help you drain out the bilge water, on the bow and/or stern.
