# 21174476 Anode Kit | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta replacement back-up anode, integrated with the transom unit, for Volvo Penta IPS installations fitted with Active Corrosion Protection. It weighs 5.588 kg and is listed for 70 applications across the D series engines and IPS pod drives. On IPS the active system replaces the standard sacrificial anodes, and this back-up anode is what carries the protection whenever the system is not driving current.

## 🚤 Compatibility

-   **Engine Family:** D, IPS
-   **HP Range:** 260-480 HP
-   **Year Range:** Approximately 2005 onward

## 🔌 Function

Corrodes preferentially to protect the IPS drives and the underwater metals bonded to them when the active corrosion protection system is not supplying current.

## ⚠️ Common Signs of Failure

-   Anode around half consumed or worse
-   Anode surface coated, insulated or no longer electrically bonded
-   Rapid or uneven consumption pointing to an electrical or galvanic fault
-   Corrosion protection alarms or faults recorded at the helm
-   Drive surfaces showing pitting, paint blistering or abnormal corrosion

## 🛠️ Service Notes

-   No anodes are consumed while the active system is running, so a back-up anode that has wasted heavily usually means the system has been in monitoring-only mode or switched off
-   Keep shore power connected while berthed: below 75% battery state of charge the system monitors only and this anode does the work, and below 50% the system is inactive
-   Fit onto clean bare metal and leave it unpainted, since bonding is what makes it work
-   Protection falls back onto this anode when the active system is in monitor-only mode or inactive
-   This is the integrated type, as distinct from the separately transom mounted back-up anode
