The Performance Metals HC3A Hull Anode is an aluminum replacement for the ZHC-3. It’s a mid-size hull anode in the HC series. Hull anodes protect everything tied into the boat’s bonding system.
Performance Metals makes its Navalloy aluminum anodes to military specification MIL-DTL-24779, and they work in salt, brackish and fresh water. Each one has Performance Metals’ patented red spot wear indicator, which shows at a glance when it’s time for a replacement. Aluminum anodes protect in salt, brackish and fresh water, and they deliver more protection per pound than zinc.
Stick with one anode metal on a given drive or hull instead of mixing zinc and aluminum. Replace anodes when they’re about half consumed, and never paint them, because paint stops them from working. Match the alloy and mounting dimensions to the existing anode before replacement, because both details affect protection and fit. Browse more marine anodes.
