Which correct fitting
What fitting are you talking about, I am intrigued? My drain kind of sucks anyway. The one time I tried to hook a hose to it to drain to the bilge, it leaked like crazy anyway. Adding the anode that way might make more sense.Actually with the correct fittings you could have both. I don't like the current drain valve anyway, very difficult to attach a drain hose fitting to because of interference with the EX input fitting from engine, or is that the return, I'm not sure it makes a difference.
