Compatibility, Size and Fit
This drain plug is described as a replacement for the Sea-Dog 520047-1 and as fitting the Sea-Dog 520046 drain socket. It is also described as compatible with standard 3/4-inch NPT marine drain plug sockets. Buyers should compare the exact thread size and the drain socket used on the boat.
