Installation Notes
- Disconnect the boat's battery before beginning work.
- Locate and remove the old, corroded anodes from the sterndrive gearhouse and transom shield.
- Thoroughly clean the mounting surfaces on the sterndrive to ensure a clean, bare metal contact. A poor connection will prevent the new anode from working correctly.
- Install the new aluminum anodes using the included hardware. Do not use old hardware.
- Tighten the bolts to the manufacturer's recommended torque specifications. Ensure the anode is secure.
- Reconnect the boat's battery. The new anodes are now active.
Troubleshooting & FAQ
What water type is this aluminum anode kit for?
Aluminum anodes are specifically designed for optimal protection in brackish and saltwater environments. They are more active than zinc, providing better protection and a longer service life in these conditions. Avoid using aluminum anodes in freshwater, where magnesium is recommended.
How do I know when my sterndrive anodes need replacing?
Anodes should be inspected at least once a year, or more frequently in aggressive saltwater environments. Replace your anodes when they are approximately 50-75% corroded. Clear signs for replacement include visible pitting, crumbling, or a significant reduction in mass. Never paint anodes, as this will render them inactive.
Will this kit fit both DPS and SX-A drives?
Yes, this kit is designed for a broad range of Volvo Penta sterndrives, including the DPS series (DPS-A, DPS-B, DPS-D), FWD drives, and the SX-A and SX-D drives. Always consult the detailed compatibility table to confirm your specific model is listed.
What's the difference between aluminum and zinc anodes?
Aluminum anodes have a higher negative voltage potential than zinc, which allows them to provide more effective cathodic protection in brackish water and saltwater. Zinc is traditionally used for saltwater only, and magnesium is used exclusively for freshwater.
