Designed for secure shaft contact and dependable sacrificial protection, this marine shaft anode uses a streamlined profile to reduce drag while helping extend the service life of running gear and other underwater metal components.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eZinc alloy construction:\u003c\/strong\u003e Ideal for saltwater applications where reliable cathodic protection is needed for prop shafts and related metal hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStreamlined two-piece design:\u003c\/strong\u003e Interlocking halves fit around the shaft for strong contact and a clean, low-drag profile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStainless steel hardware:\u003c\/strong\u003e Includes Allen head fasteners and retaining hardware for secure installation and dependable hold.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBoat owners choose Martyr anodes for their consistent casting quality and marine corrosion protection. This shaft anode is designed to mount directly over the propeller shaft, where it sacrifices itself before more valuable underwater metals can corrode. The streamlined shape supports efficient performance, while the precision fit helps maintain even contact around the shaft.\u003c\/p\u003e\u003cp\u003eMartyr offers this zinc shaft anode in multiple imperial shaft sizes, making it a practical choice for a wide range of inboard boats. If your vessel operates primarily in salt water, a Martyr zinc anode is the proper material choice; for brackish or fresh water applications, alternative anode alloys may be more appropriate. Always match the anode size to your shaft diameter for the best fit and protection.\u003c\/p\u003e","brand":"The Harbour Chandler","offers":[{"title":"3\/4\"","offer_id":47513831735474,"sku":"CMX01","price":18.49,"currency_code":"CAD","in_stock":true},{"title":"7\/8\"","offer_id":47513831997618,"sku":"CMX02","price":18.99,"currency_code":"CAD","in_stock":true},{"title":"1\"","offer_id":47513831702706,"sku":"CMX03","price":16.49,"currency_code":"CAD","in_stock":true},{"title":"1-1\/8\"","offer_id":47513831866546,"sku":"CMX04","price":17.49,"currency_code":"CAD","in_stock":true},{"title":"1-1\/4\"","offer_id":47513832030386,"sku":"CMX05","price":22.59,"currency_code":"CAD","in_stock":true},{"title":"1-3\/8\"","offer_id":47513831833778,"sku":"CMX06","price":24.99,"currency_code":"CAD","in_stock":true},{"title":"1-1\/2\"","offer_id":47513831768242,"sku":"CMX07","price":22.59,"currency_code":"CAD","in_stock":true},{"title":"1-3\/4\"","offer_id":47513831932082,"sku":"CMX08","price":39.99,"currency_code":"CAD","in_stock":true},{"title":"2\"","offer_id":47513831964850,"sku":"CMX09","price":39.99,"currency_code":"CAD","in_stock":true},{"title":"2-1\/4\"","offer_id":47513831801010,"sku":"CMX10","price":89.99,"currency_code":"CAD","in_stock":true},{"title":"2-1\/2\"","offer_id":47513831899314,"sku":"CMX11","price":42.63,"currency_code":"CAD","in_stock":true},{"title":"2-3\/4\"","offer_id":47718983205042,"sku":"CMX12","price":92.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/3028\/8562\/files\/12238484-1.jpg?v=1779722001","url":"https:\/\/www.harbourchandler.ca\/products\/martyr-zinc-streamlined-shaft-anode","provider":"The Harbour Chandler","version":"1.0","type":"link"}
