24007660 873395 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 aluminium anode listed for intermediate housing, DPX drives, supplied for salt and brackish water.

🚤 Compatibility

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

⚙️ Key Features

• Intermediate housing anode for the DPX duo prop drives
• Aluminium, for salt and brackish water
• 0.163 kg
• Supersedes 873395, an earlier zinc electrode
• Fresh water equivalent is magnesium anode 3863480
• Quantity varies by assembly, most commonly two
• Aluminium anode for Intermediate housing, DPX drives.
• Listed for salt and brackish water.
• Aluminium anodes give 30% higher corrosion protection capacity than a similarly sized zinc anode.
• Up to 20-40% longer life span in salt water than a similarly sized zinc anode.
• Lower environmental impact, and the better choice for brackish water as well as salt.
• Aluminium anodes can be used for all types of hull material.
• 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.
• Material: aluminium
• Fits: Intermediate housing, DPX drives
• Aluminium sacrificial anode for the intermediate house position
• Fits the Aquamatic duo prop DPX drives
• Position: intermediate house
• Water type: Salt and brackish water
• Fits: the Aquamatic duo prop DPX drives

🔌 Function

Corrodes in place of the drive, giving up its own metal to the galvanic circuit so the aluminium castings, gears and fasteners around it are left alone.

⚠️ Common Signs of Failure

• Anode wasted away, deeply pitted, or gone altogether
• White corrosion blooms or paint lifting on the drive castings
• Anode still bright after a season, which means it is not making electrical contact
• Fixings corroded into the housing so the anode cannot be removed
• Pitting starting on the drive leg itself

🛠️ Service Notes

• Renew when about half consumed rather than waiting for it to disappear
• Fit onto clean bare metal with no paint, grease or sealant behind it - an insulated anode protects nothing
• The DPX spray plate takes zinc anode 876638 and the transom shield takes 23813192 or 24042665, so order by position
• 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
