The Sierra 18-6125A Aluminum Transom Plate Anode is a direct-replacement sacrificial anode designed to protect the transom and stern drive components of Volvo Penta and OMC stern drive systems from galvanic corrosion. By sacrificing itself through electrochemical action, this anode shields expensive metal components from premature deterioration.
Aluminum Construction: Aluminum anodes are the preferred choice for boats operated in brackish water, or for vessels that move between fresh and salt water environments. Unlike zinc anodes, aluminum provides effective protection across a wider range of water salinities.
Key Features:
Sierra International is a leading manufacturer of aftermarket marine engine parts and accessories, offering OEM-quality replacements at competitive prices. Replace worn or depleted anodes regularly to maintain continuous protection for your stern drive and transom hardware.
Cross Reference / Replaces: Volvo Penta 3586461, CMP CM3854130A, Tecnoseal 00718AL
