![cheras-1500x1500](https://www.rhsboating.com.au/images/com_hikashop/upload/cheras-1500x1500.jpg)  Maintain your boat's sacrificial anode system with Cheras marine zinc anodes. RWB lists Australian-made Cheras anodes in different shapes and sizes, including propeller shaft models. Choose replacements by the required material, shaft or mounting dimensions and application. Checking the existing anode specification helps you select the correct component for your vessel's corrosion-protection system. Explore the Cheras listings at RHS Boating & Marine for product details and available options.
