{"product_id":"876604-magnesium-anode-kit-genuine-volvo-penta","title":"876604 Magnesium Anode Kit | Genuine Volvo Penta Part","description":"\u003ch2\u003e\n 🔧 Product Description\n\u003c\/h2\u003e\n\u003cp\u003e\n Genuine Volvo Penta anodes are made to sacrifice themselves in order to protect the drive and propeller from galvanic corrosion. Volvo Penta now recommends aluminium anodes in salt and brackish water instead of the zinc previously recommended for salt water, and is gradually phasing out and replacing most of its zinc anodes with aluminium ones. Aluminium anodes give 30% higher corrosion protection capacity, up to 20-40% longer life span in salt water compared with similarly sized zinc anodes, a lower environmental impact, and are the better choice for brackish water too. Magnesium is the material listed for fresh water. This is the magnesium anode listed for lower gear, S-drive 120S, MS25S, supplied for fresh water.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  D, TMD, MS, MD\n \u003c\/li\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   HP Range:\n  \u003c\/strong\u003e\n  13-75 HP\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\n Full model list at the end of this description.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Lower gear anode for the 120S and MS25S saildrives\n \u003c\/li\u003e\n \u003cli\u003e\n  Magnesium, for fresh water\n \u003c\/li\u003e\n \u003cli\u003e\n  0.191 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Salt and brackish water equivalent is aluminium anode 23973978\n \u003c\/li\u003e\n \u003cli\u003e\n  Not included with the lower gear\n \u003c\/li\u003e\n \u003cli\u003e\n  Magnesium anode for Lower gear, S-drive 120S, MS25S.\n \u003c\/li\u003e\n \u003cli\u003e\n  Listed for fresh water.\n \u003c\/li\u003e\n \u003cli\u003e\n  Aluminium anodes give 30% higher corrosion protection capacity than a similarly sized zinc anode.\n \u003c\/li\u003e\n \u003cli\u003e\n  Up to 20-40% longer life span in salt water than a similarly sized zinc anode.\n \u003c\/li\u003e\n \u003cli\u003e\n  Lower environmental impact, and the better choice for brackish water as well as salt.\n \u003c\/li\u003e\n \u003cli\u003e\n  Aluminium anodes can be used for all types of hull material.\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta anodes feature, where needed, an internal reinforcement made from an alloy that does not erode, which also ensures a reliable electrical connection between the anode and the drive.\n \u003c\/li\u003e\n \u003cli\u003e\n  Material: magnesium\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits: Lower gear, S-drive 120S, MS25S\n \u003c\/li\u003e\n \u003cli\u003e\n  Magnesium sacrificial anode for the lower gear position\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits the 120S and MS25S saildrives\n \u003c\/li\u003e\n \u003cli\u003e\n  Position: lower gear\n \u003c\/li\u003e\n \u003cli\u003e\n  Water type: Fresh water\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits: the 120S and MS25S saildrives\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Corrodes in place of the drive housing, taking the electrolytic attack that would otherwise fall on the aluminium.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Anode eaten down to a stub well before the next lift-out\n \u003c\/li\u003e\n \u003cli\u003e\n  White powdery corrosion product around the anode seat\n \u003c\/li\u003e\n \u003cli\u003e\n  An anode that looks untouched after a full season, pointing to a broken bonding path\n \u003c\/li\u003e\n \u003cli\u003e\n  White pitting or blistering paint on the drive leg\n \u003c\/li\u003e\n \u003cli\u003e\n  Corrosion appearing at the propeller or shaft end\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Magnesium is for fresh water only and will be consumed very fast in salt water, so match the material to where the boat lies\n \u003c\/li\u003e\n \u003cli\u003e\n  Anode 876603 is the fresh water anode for the 110S lower gear, so confirm the drive model before ordering\n \u003c\/li\u003e\n \u003cli\u003e\n  Clean the seating face to bright metal, check the bonding continuity and never paint over the anode\n \u003c\/li\u003e\n \u003cli\u003e\n  Salt and brackish water: aluminium (or, on some older drives, cadmium-free zinc marked Zn).
