Do these plugs need thread tape on them? When I pop the cover after running the boat one of mine has a drip coming off of it. I checked it and its tight.

It's probably just rusty. Do you leave the plugs out for winter?
Clean the threads and use some gasket sealer on the plug (NOT teflon tape) the sealer will prevent future rust. Also, put the plugs back in after draining, then the threads won't get all rusty.

We just bought the boat. I removed the drain plug when I saw the drip and reinstalled the plug. The threads were not rusty. Ill try some thread sealer. It was always winterized, the mechanic that did it was there when I bought it, plus I have reciepts.
