B & S Anodes Rudder Button Zinc Anode

The B & S Anodes Rudder Button Zinc Anode is a sacrificial zinc anode that protects rudders, trim tabs and other underwater metal parts from galvanic corrosion. Galvanic corrosion happens when dissimilar metals sit together in salt water. Zinc is the less noble metal, so it corrodes first and the metal parts you want to protect last longer. This button-style anode is also sold as a rudder zinc or trim tab zinc.

Key Features:

• Zinc alloy made to Federal Specification MIL-A-18001K
• Hand-poured in the U.S.A. by B & S, a company with about 50 years of experience making zinc anodes
• Button design for rudders and trim tabs
• Comes with stainless steel mounting hardware, as the manufacturer supplies it

Replace the anode when it has mostly corroded away. That keeps your rudder and other underwater hardware protected season after season.
