Martyr Anodes Rudder/Trim Tab Anode with Stainless Steel Allen Head Screw Anodes/Zincs

The Martyr Anodes Rudder/Trim Tab Anode with Stainless Steel Allen Head Screw is a sacrificial anode (often called a rudder zinc or trim tab zinc) that helps protect your boat's underwater metals from galvanic corrosion. Mounted on a rudder or trim tab, it corrodes first, so the more valuable metal parts stay intact.

Key Features:

• Disc-style sacrificial anode made for rudders and trim tabs
• Stainless steel Allen head screw for mounting
• Available in zinc, aluminum and magnesium to suit different water conditions, such as salt, brackish or fresh water
• Made by Martyr Anodes (Canada Metal), a well-known maker of marine anodes
• Simple installation with common hand tools

Check the anode for wear regularly and replace it before it is used up. That keeps your rudder, trim tabs and other underwater hardware protected through the boating season. Choose the size and material that match your rudder or trim tab and the water you boat in.
