Martyr Anodes Aluminum Rudder and Trim Tab Anode

The Martyr Anodes Aluminum Rudder and Trim Tab Anode is a disc-style sacrificial anode. It helps protect your boat's rudders and trim tabs from galvanic corrosion. Aluminum alloy anodes are made for salt and brackish water. The anode corrodes in place of your boat's metal underwater parts, which helps limit pitting and extends the life of those parts.

Key Features:

• Aluminum alloy construction for use in salt and brackish (mixed) water
• Pressure die-cast and made from an alloy based on US Military alloy specifications
• Stainless steel hardware with an Allen head screw for secure mounting
• Bolt retaining washers help keep the anode from falling off
• Easy installation, which can be done underwater
• Made with no added cadmium, and with a low-impurity alloy that helps maintain protective performance

Martyr anodes are made under an ISO 9001 quality management system. Do not paint the anode, because paint stops it from working. Replace it when it has mostly worn away to keep corrosion protection in place.
