Is there a better quality Brass T- Drain Plug than the ones you buy from Sea D-g. I have already stripped two of these tightening them in the drain tube.Yesterday i was checking the drain plugs and one was kinda lose..i had to re-tighten it almost one complete turn. I do not know how it had became lose.. The new T-Drain Plugs that they sell are really inferior to the ones that they used to make even 10 years ago. Does anyone know who makes a better quality drain plug. ....If need be is it possibe to take out the old drain plug and replace with a new one while the boat is in the water. Thanks Tug
