Performance Metals Aluminum Trim Tab Hull Anode

The Performance Metals Trim Tab/Hull Anode is a compact aluminum anode for trim tabs and many other hull applications. It replaces the A-24. Trim tabs are often a boat's most exposed piece of underwater metal.

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.
