Thanks, Capt Bill. I appreciate your input from experience. Can you tell me how long the magnesium generally lasts in fresh? Is there a specific preferred grade of mag that is recommended? Is my routine of often wire brushing zinc recommended for mag... to help keep it at top performance level? Next anode redo I currently plan to change to mag. - Enjoy upcoming your 4th O' July!! - W.
