Magnesium is the only alloy with sufficient electrochemical activity to protect your shaft in low-conductivity freshwater — zinc and aluminum anodes go passive in freshwater and provide little to no galvanic protection. The streamlined, hydrodynamic profile keeps drag to a minimum, and the stainless steel Allen head screw holds the anode firmly in place all season.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1-1\/4\" (32mm) diameter prop shafts\u003c\/li\u003e\n\u003cli\u003eFreshwater use only (lakes, rivers, reservoirs)\u003c\/li\u003e\n\u003cli\u003eInboard and inboard\/outboard (I\/O) vessels\u003c\/li\u003e\n\u003cli\u003eReplaces OEM shaft anodes on most standard 1-1\/4\" shaft configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e CMX05M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 194-CMX05M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Magnesium alloy (sacrificial)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter:\u003c\/strong\u003e 1-1\/4\" (32mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener:\u003c\/strong\u003e Stainless steel Allen head screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Streamlined \/ hydrodynamic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest For:\u003c\/strong\u003e Freshwater only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e ~190 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAlso Available In\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/martyr-cmx05-zinc-streamline-shaft-anode-1-1-4in-194-cmx05\"\u003eCMX05 – 1-1\/4\" Zinc\u003c\/a\u003e (saltwater)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/martyr-cmx05a-zinc-streamline-shaft-anode-1-1-4in-ext-heavy-194-cmx05a\"\u003eCMX05A – 1-1\/4\" Zinc Extended Heavy\u003c\/a\u003e (saltwater, extended service)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAdjacent Sizes – Magnesium\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/martyr-cmx04m-magnesium-streamline-shaft-anode-1-1-8in-194-cmx04m\"\u003eCMX04M – 1-1\/8\" Magnesium Shaft Anode\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/martyr-cmx06m-streamlined-shaft-anode-with-stainless-steel-allen-head-magnesium-194-cmx06m\"\u003eCMX06M – 1-3\/8\" Magnesium Shaft Anode\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/cmx03m-1-shaft-anode-magnesium-194-cmx03m\"\u003eCMX03M – 1\" Magnesium Shaft Anode\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003eThe CMX05M is the right anode for any 1-1\/4\" shaft running in freshwater. The 1-1\/4\" shaft is one of the most common sizes on mid-range inboard cruisers and workboats, and it’s also one of the sizes where we most frequently see zinc anodes installed on freshwater vessels. Zinc simply doesn’t work in freshwater — it passivates and stops sacrificing, leaving the shaft and cutlass bearing unprotected. If you’re seeing corrosion on a freshwater vessel with zinc shaft anodes, switching to magnesium is the fix.\u003c\/p\u003e\n\u003cp\u003eFor saltwater or brackish water, use the \u003ca href=\"\/products\/martyr-cmx05-zinc-streamline-shaft-anode-1-1-4in-194-cmx05\"\u003eCMX05 zinc\u003c\/a\u003e (saltwater) or an aluminum version for brackish conditions.
