<p><strong>Boat anodes</strong>, also known as <strong>galvanic or sacrificial anodes</strong>, are essential components that protect metal parts of a boat from electrochemical corrosion.</p>
    [additional_description] => <h3>Function of Anodes</h3>
<p>The main function of anodes is to prevent corrosion. They should be replaced at least once per season, and more frequently in harsher marine conditions. Anodes are typically installed along the keel, rudder, or propeller shaft.</p>
<p><strong>Important</strong>: Never paint, brush, or grease the anodes! This would reduce their electrical conductivity with water, rendering them ineffective against corrosion. If your boat stays out of the water for long periods, oxidation may form (especially on aluminum anodes), reducing performance. In these cases, replacement is necessary.</p>
