- Thoroughly clean the mounting surfaces on the outdrive, ensuring they are free of corrosion, paint, and residue for a clean metal-to-metal contact.

Troubleshooting & FAQ
What is this anode kit used for?
This anode kit is used in saltwater to prevent galvanic corrosion on a Volvo Penta 280 single-prop outdrive, sacrificing itself to protect more valuable metal components of the drive.
How do I confirm if this fits my specific Volvo Penta 280?
This kit fits the single-propeller version of the Volvo Penta 280 outdrive, manufactured from 1973 to present. Cross-reference your existing part number with the ones listed in the Part Number Matrix to ensure compatibility.
How often should I replace these zinc anodes?
Anodes should be inspected during regular maintenance intervals (at least annually) and replaced when they are 50% consumed. Replacement frequency depends on water salinity, temperature, and electrical activity around the dock.
What are the signs that my anodes need replacing?
Visible signs include severe pitting, crumbling, or significant reduction in size. If you notice accelerated corrosion on other underwater metal parts of your outdrive, your anodes may be depleted or not making proper contact.
Can I use this zinc kit in freshwater or brackish water?
This kit is made of zinc, which is specifically formulated for optimal protection in saltwater. For freshwater, aluminum anodes are recommended, and for brackish water, aluminum or magnesium may be more effective.
