21194277 Anode | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta sacrificial anode assembly installed in the exhaust system of 3.0GXi-J and 3.0GXiC-J petrol engines. Three anodes are used in the applicable exhaust arrangement. The anode protects the water-jacketed exhaust components from galvanic corrosion and is supplied as the specified plug-anode-and-seal assembly.

🚤 Compatibility

Typically suits:

• Volvo Penta 3.0GXiC-J
• Volvo Penta 3.0GXi-J

• HP Range: Approximately 135 HP

• Three anodes used in the applicable exhaust assembly
• Protects the exhaust riser and water jacket from galvanic attack
• Inspect at regular service intervals and replace before fully consumed
• Engine type: Volvo Penta 3.0-litre inline-four petrol sterndrive engine
• 3 used per assembly

🔌 Function

Sacrifices its own metal to protect the water-cooled exhaust casting from galvanic and electrolytic corrosion.

⚠️ Common Signs of Failure

• Anode material consumed beyond the service limit
• Uneven wastage, deep pitting or complete loss of the element
• Corrosion appearing on the protected exhaust component
• Loose plug, damaged threads or leakage at the seal
• Little or no anode consumption caused by poor electrical contact

🛠️ Service Notes

• Clean the anode's seat back to bare, sound metal — no paint, antifouling, oil, sealant or corrosion product — because the anode only works if it is in good electrical contact with what it is protecting
• Never paint or antifoul the anode itself, or the area it sits on; do make good the surrounding factory coating so the anode is not being asked to protect bare metal it was never sized for
• Fit with clean fasteners and check the fasteners themselves make good contact; fit the anode dry against its seat rather than bedding it on sealant
• Inspect anodes at every lift or service and renew them once roughly half the anode has wasted away — a heavily consumed anode has too little metal left to give useful protection
• If anodes are disappearing much faster than usual, or barely wasting at all, investigate the installation's bonding and shore power earthing rather than just fitting more anodes
