Aluminum anodes are preferred for brackish water, and magnesium anodes are used in freshwater. Using the wrong anode material for your water type reduces protection effectiveness.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I replace just one anode instead of the full kit?\u003c\/strong\u003e\u003cbr\u003eYou can, but replacing the full kit ensures even protection across the entire drive. Mixing old and new anodes of different depletion levels can result in uneven corrosion protection. A full kit replacement is the recommended practice.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to remove the drive to replace the anodes?\u003c\/strong\u003e\u003cbr\u003eSome anodes are accessible with the drive in the water; others require haul-out. Refer to the Volvo Penta service manual for your specific drive model for the correct procedure.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eAnode replacement is one of the most skipped items in annual sterndrive service, and it’s one of the most expensive mistakes you can make. We regularly see SX drives with significant corrosion damage that could have been prevented with a $100 anode kit. If you’re already hauling the boat for service, replacing the full kit at the same time is always the right call — the labour is already there. One thing to watch: make sure the mounting surfaces are clean bare metal before installing. Anodes mounted over paint or corrosion don’t make proper electrical contact and won’t protect the drive effectively.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564003721252,"sku":"3588770","price":111.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/9678372a-4855-4174-918a-bd5467ddf0fd.png?v=1775259791","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-sx-sterndrive-zinc-anode-kit-3588770","provider":"Marisol Marine Company","version":"1.0","type":"link"}
