A depleted prop nut anode leaves the shaft threads and propeller nut exposed to galvanic attack, which can make future prop removal significantly harder and lead to corrosion damage on the shaft itself.\u003c\/p\u003e\n\u003cp\u003eThe most important step before ordering is confirming your prop nut style. Martyr’s lettered series (A, B, C, D, F, H) correspond to different prop nut geometries — the wrong series won’t fit correctly and won’t make proper electrical contact. If you’re unsure of your series, bring the old anode or the prop nut itself to a marine dealer for comparison before ordering.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":50999092576292,"sku":"194-CMPNZC","price":21.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/194-CMPNZD_361c375e-96e8-4a71-a197-e545971febc4.jpg?v=1782799309","url":"https:\/\/marisolmarine.com\/products\/martyr-cmpnzc-zinc-prop-nut-anode-series-c-194-cmpnzc","provider":"Marisol Marine Company","version":"1.0","type":"link"}
