I am rebuilding my 44' Steel 1959 Phillip Rhodes Motor-Sailor. The main water tanks (175 Gallons capacity) are sheet metal Monel and appear to be brazed or soldered joints. Despite being over 40 years old the tanks are in excellent condition . . . no signs of corrosion at all. Does anybody know about this material . . . should I be able to continue to use these as potable water tanks, or am I going to die of some heavy metal malady. P.S. My boat has another "reserve" tank that holds 170 gallons. You got to love a boat with 170 "reserve" gallons of water!
