Description

The Volvo Penta 21174476 is a genuine OEM zinc anode kit for select IPS pod drive applications. Current Volvo Penta references identify it as part of the Active Corrosion Protection (ACP) system, and current product references describe it as the back-up anode used to help protect the drive unit, propeller system, and related underwater metal components from galvanic corrosion.

This is the zinc version of the kit, making it the correct traditional material choice for saltwater use. Current dimension references list the anode at approximately 350 mm long x 84 mm wide, with 10.5 mm mounting holes and 150 mm hole centers.

Engine Compatibility
Current fitment references associate 21174476 with select Volvo Penta IPS-A, IPS-B, IPS-C, IPS-D, IPS-E, IPS-F, IPS15-A, IPS15-B, IPS2-A, IPS2-B, IPS2-C, IPS20-D, IPS3-A, IPS3-C, and IPS30-D pod drive applications. Current references also describe it for Twin, Triple, and Quadruple drive ACP systems.

Serial Number Fitment Notice
Fitment should be verified by Volvo Penta IPS model, serial number, installed anode location, and mounting dimensions before ordering. Matching by OEM part number 21174476 remains the safest method.

When This Part Needs Replacement
Replace this anode when it is heavily wasted, pitted, cracked, loose, or significantly reduced in size. As part of the IPS ACP system, it should be inspected regularly so corrosion protection is maintained before the sacrificial material is too far consumed.

Installation Notes
Install on a clean bare-metal contact surface and do not paint the anode. Current references conflict on hardware inclusion, with some indicating hardware included and others indicating hardware not included, so stocked contents should be verified before fulfillment.

Parts Desk Insight
This is not just a standard loose drive anode. It is tied to Volvo Penta’s IPS Active Corrosion Protection setup, which makes correct part-number matching especially important. The big practical point is that this anode protects a very expensive IPS system, so replacing it on schedule is far cheaper than dealing with corrosion damage later.
