Zinc anodes like 3888817 are designed for saltwater. If your boat operates primarily in freshwater, a zinc anode can actually reduce protection compared to the correct magnesium alternative (3888818). If you’re in brackish or mixed water, the aluminum option (23164611) is the better fit. Always confirm your water type before selecting an anode.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564037570596,"sku":"3888817","price":78.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/8dbadfc0-0d99-4708-9112-d12ba75e4a5a.png?v=1788717820","url":"https:\/\/marisolmarine.com\/products\/volvo-900","provider":"Marisol Marine Company","version":"1.0","type":"link"}
