{"product_id":"23974010-anode-kit-genuine-volvo-penta","title":"23974010 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 aluminium anode listed for lower gear, 280, 290, DP drives, supplied for salt and brackish 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  MD, TMD, AD, AQAD, D, AQ, TAMD, BB, DP, SP, MS, AQD, KAD, KAMD\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 duo prop 280, 290 and DP drives\n \u003c\/li\u003e\n \u003cli\u003e\n  Aluminium, for salt and brackish water\n \u003c\/li\u003e\n \u003cli\u003e\n  0.202 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Replaces the earlier 875821\n \u003c\/li\u003e\n \u003cli\u003e\n  Fresh water equivalent is magnesium anode 876138\n \u003c\/li\u003e\n \u003cli\u003e\n  Aluminium anode for Lower gear, 280, 290, DP drives.\n \u003c\/li\u003e\n \u003cli\u003e\n  Listed for salt and brackish 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: aluminium\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits: Lower gear, 280, 290, DP drives\n \u003c\/li\u003e\n \u003cli\u003e\n  Aluminium sacrificial anode for the lower gear position\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits the Aquamatic duo prop 280, 290 and DP drives\n \u003c\/li\u003e\n \u003cli\u003e\n  Position: lower gear\n \u003c\/li\u003e\n \u003cli\u003e\n  Water type: Salt and brackish water\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits: the Aquamatic duo prop 280, 290 and DP drives\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📋 Kit Contents\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  1 × aluminium ring anode - 23974010\n \u003c\/li\u003e\n \u003cli\u003e\n  Mounting screws are separate unless specifically supplied with the installation\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Provides sacrificial corrosion protection for the propeller shaft and lower gear assembly.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Anode consumed to around half its original size\n \u003c\/li\u003e\n \u003cli\u003e\n  Deep pitting, cracking or uneven erosion\n \u003c\/li\u003e\n \u003cli\u003e\n  Loose mounting or poor metal-to-metal contact\n \u003c\/li\u003e\n \u003cli\u003e\n  Corrosion forming on the propeller shaft or gear housing\n \u003c\/li\u003e\n \u003cli\u003e\n  Damaged or missing mounting hardware\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  Confirm the drive turns two propellers - the single prop and SP lower gear takes a different anode\n \u003c\/li\u003e\n \u003cli\u003e\n  Aluminium is now Volvo Penta's recommended material for salt and brackish water in place of zinc, with around 30% more protection capacity\n \u003c\/li\u003e\n \u003cli\u003e\n  Fit against clean bare metal, leave unpainted, and reactivate a long-stored anode with emery paper rather than a wire brush\n \u003c\/li\u003e\n \u003cli\u003e\n  Salt and brackish water: aluminium (or, on some older drives, cadmium-free zinc marked Zn).
