B & S Anodes Rudder Zinc Anode

The B & S Anodes Rudder Zinc Anode (also called a rudder button anode or trim tab zinc) is a sacrificial zinc anode. It protects underwater metal parts from galvanic corrosion. When different metals sit in salt water, the less noble metal corrodes first. The zinc corrodes in its place, which helps protect your rudder and trim tab hardware.

Key Features:

• Cast from zinc alloy that meets Military Specification MIL-A-18001K
• Hand-poured in the U.S.A. by B&S Marine Anodes
• Two-piece, button-style design for rudders and trim tabs
• Supplied with a stainless steel Allen head bolt for mounting

B&S has been making zinc anodes for decades, and its roots go back to Bossler & Sweezey, a Long Island marine hardware company. Check the anode regularly and replace it before it wears away. That keeps your rudder protected.
