The Volvo Penta 23520859 is a genuine OEM aluminum anode for select Volvo Penta sterndrive applications. Volvo Penta’s official parts shop identifies 23520859 as an anode for Aquamatic sterndrive duo-prop drive DPI, DPH, and DPR, specifically for the spray plate location.
Because this is an aluminum anode, it is the correct material choice for saltwater and brackish water use. Volvo Penta states that its aluminum anodes are more efficient than zinc and are recommended for both salt and brackish water applications.
Key Features
- Genuine Volvo Penta OEM anode kit

Engine Compatibility
Current fitment references identify 23520859 for select Volvo Penta DPI, DPH, and DPR Aquamatic sterndrives, with multiple current sources also describing it as a DPI-A cavitation plate anode. Fitment should still be confirmed against the exact drive model and serial number before ordering.
Serial Number Fitment Notice
Please verify fitment using the Volvo Penta drive model and serial number before ordering. This is the safest way to confirm the correct anode, especially on serviced drives where installed components may differ from the original setup. Matching by OEM part number 23520859 remains the best method.
When This Part Needs Replacement
Replace this anode when it is heavily wasted, pitted, loose, cracked, or significantly reduced in size. Volvo Penta recommends inspecting anodes regularly, and some current product references suggest replacement once the anode is noticeably worn to maintain proper corrosion protection.
Installation Notes
Install on a clean bare-metal contact surface and do not paint the anode. Current seller references describe this as the spray plate / cavitation plate anode, and at least one current listing notes that mounting hardware is not included, so included contents should be confirmed before ordering.

One useful detail is that Volvo Penta now promotes aluminum over zinc for salt and brackish water, making 23520859 the correct modern OEM material choice for those environments.
