3863480 Anode | Genuine Volvo Penta Part

🔧 Product Description

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 intermediate housing, DPX drives, supplied for fresh water.

🚤 Compatibility

• Engine Family: TSK, DPX, DP, SX, TAMD, KAD, KAMD

🔌 Function

Corrodes in place of the drive castings, protecting them from galvanic attack.

⚠️ Common Signs of Failure

• Anode wasted away or more than half gone
• White powdery crust over the anode face
• Paint blistering or pitting on the drive castings nearby
• Anode still bright and untouched, which means it is not earthing
• Fixing screw corroded solid

🛠️ Service Notes

• Magnesium suits fresh water; in salt or brackish water fit aluminium anode 24007660 instead
• Never paint an anode, and clean the seat back to bare metal so it earths to the housing
• Renew once about half wasted rather than waiting for it to disappear
• Salt and brackish water: aluminium (or, on some older drives, cadmium-free zinc marked Zn). Fresh water: magnesium.
• When installing a new anode it is important to have good contact between the anode and the surface to which it is connected.
• If an anode has been exposed to air for a long time it can be covered by a passivating surface film that prevents it working properly; consider reactivating it with emery paper before launching. Do not use sandpaper, a wire brush or other steel tools when cleaning, as these may damage the galvanic protection.
• Water flow, salinity, temperature, pollution levels and stray current considerably affect anode life.
• Read the operator's manual for detailed information on maintaining and replacing anodes.
• Volvo Penta now recommends aluminium anodes in salt and brackish water, in place of the zinc previously recommended for salt water
• Aluminium anodes are listed as giving 30% higher corrosion protection capacity and up to 20-40% longer life in salt water than similarly sized zinc anodes, with lower environmental impact, and as the better choice for brackish water too
• Magnesium is the material listed for fresh water
• For some older drives, cadmium-free zinc anodes, marked Zn, are supplied for salt and brackish water instead of aluminium
• Volvo Penta anodes carry, where needed, an internal reinforcement in an alloy that does not erode, which also keeps a reliable electrical connection between the anode and the drive
• An anode that has been exposed to air for a long time can be covered by a passivating surface film that stops it working properly; consider reactivating it with emery paper before launching the boat
