Troubleshooting & FAQ
How do I know if this anode kit will fit my sterndrive?
This kit is specifically for the Volvo Penta 280 Duo Prop series sterndrive. The best way to confirm fitment is to match the OEM part numbers (875821, 832598) or any of the listed aftermarket cross-reference numbers to your existing parts or service manual.
When should I replace my sterndrive anodes?
Anodes should be inspected at least annually, or every time you haul the boat. Replace them when they appear to be 50% eroded. Waiting longer can leave your expensive sterndrive components unprotected.
What are signs of a failing anode?
If you notice accelerated corrosion, pitting, or paint blistering on your sterndrive, propeller, or trim tabs, it's a strong sign your anodes are depleted or not working correctly. A functioning anode will show visible signs of corrosion and erosion over time an "eaten away" look.
Can I use this zinc anode kit in fresh or brackish water?
No. Zinc anodes are designed exclusively for saltwater. In freshwater, they can develop a calcareous coating that passivates them, rendering them ineffective. For fresh or brackish water, you should use aluminum or magnesium anode kits.
Is it okay if there's a gap between the anode and the drive?
No, there must be a direct, secure, metal-to-metal connection for the anode to provide galvanic protection. Clean the mounting surface thoroughly before installing and tighten bolts to the manufacturer's recommended torque.
