The most common mistake with hull plate anodes is ordering by overall size without checking the bolt hole spacing first; always confirm the center-to-center hole dimension matches your hull's existing pattern before ordering. For vessels operating in brackish or mixed-salinity water, consider an aluminum hull anode instead — zinc can passivate in lower-salinity conditions and lose effectiveness.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":50999088644132,"sku":"194-CMMZC406","price":124.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/194-CMMZC406.jpg?v=1782799281","url":"https:\/\/marisolmarine.com\/products\/martyr-cmmzc406-zinc-hull-plate-anode-4-4x9-194-cmmzc406","provider":"Marisol Marine Company","version":"1.0","type":"link"}
