Performance Metals HC5A Aluminum Hull Anode

The Performance Metals HC5A is a large aluminum hull anode that replaces the ZHC-5. Bigger anodes last longer between haul-outs on larger boats. It mounts through the hull and connects to the 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.

Replace anodes when they're about half consumed, and never paint them, because paint stops them from working. Clean the mounting surface to bare metal before installing so the anode makes good electrical contact. Use one appropriate anode alloy for the water conditions and installation rather than mixing materials on the same protected system. Browse more marine anodes.
