Inquiry (采购产品): Hull Anode How do I visually tell whether I have a zinc, magnezium or aluminum anode installed on the transom of my boat? The only writing that I can see is "CAMP" and "Do Not Paint" It measures 4.75" x 8.25 x 1.25" and it bolts on. **** Hidden Message ***** Ken Edwards K0H 1Y0 Company: The Electrical Doctor E-mail: electricaldoctor@bellnet.ca **** Hidden Message ***** electricaldoctor@bellnet.ca
