🔌 Function

Corrodes in place of the surrounding metal, giving up its own material to protect the engine's raw-water side from galvanic attack.

⚠️ Common Signs of Failure

• Anode wasted away to a stub or gone entirely at service
• Anode still full size after a season, which suggests it is not making contact
• Corrosion appearing on the metal the anode should be protecting
• Thread or seat corroded so the anode cannot make a clean bond
• Coolant or raw water weeping at the anode joint

🛠️ Service Notes

• Check the anode at every service and renew it once around half consumed rather than waiting for it to disappear
• Good contact between the anode and the surface it screws into is what makes it work - fit metal to metal, with no sealant or paint on the mating face
• Plug 838928 is usually renewed alongside it
• Always refer to the operator's manual for the recommended maintenance and service intervals for your engine and drive
• Listed against more than one engine or drive family - check the qualifier that applies to your own engine or drive
