875809 Zinc Ring Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta zinc ring kit from the Marine Propulsion group, weighing 0.24 kg. It supersedes part number 897339, catalogued earlier as corrosion protection. Its listing carries no engine applications, so it must be ordered by part number or through the superseded number against your drive's parts list — the other zinc ring kit in this run, 875805, is a separate part with its own listing and is not a substitute.

⚙️ Key Features

• 0.24 kg
• Supersedes 897339, catalogued earlier as corrosion protection
• Marine Propulsion group
• No engine applications listed — order by part number

🔌 Function

Corrodes sacrificially in place of the surrounding metal, taking the galvanic attack that would otherwise fall on the drive components.

⚠️ Common Signs of Failure

• Ring wasted, pitted or reduced to a fraction of its original section
• Ring missing entirely with only its fixing left in place
• White or grey oxide crust insulating the surface from the water
• Corrosion or pitting beginning on the surrounding metal
• Ring loose on its fixing and no longer making electrical contact

🛠️ Service Notes

• Order by part number or through the superseded number 897339 — nothing in this kit's listing names an engine
• Renew once about half the section has wasted, and fit to clean bare metal with no paint or sealant on the contact face
