Installation Notes
- Before starting, disconnect the boat's battery for safety.
- Carefully remove the old, corroded anodes from the outdrive. You may need to clean the screw heads to get a good grip.
- Thoroughly clean the mounting surface on the outdrive where the new anodes will sit. A wire brush works well to remove any residue or buildup.
- Ensure a direct, clean metal-to-metal contact between the new anode and the outdrive. This is critical for proper cathodic protection.
- Securely fasten the new ring and bar anodes using the included mounting hardware. Do not overtighten the screws.
- Never paint an anode or the surface it mounts to, as this will render it ineffective.
- Once installation is complete, you may reconnect the battery.
Troubleshooting & FAQ
How do I know if this kit fits my Volvo Penta outdrive?
This kit is specifically designed for Volvo Penta 280 Duo Prop (280DP) and 200-280 Series Duo Prop outdrives. The best way to confirm fitment is to check your existing parts for the OEM numbers 875821 (ring) and 832598 (bar).
When should I replace my zinc anodes?
Anodes should be inspected at least once a year and replaced when they are 50-60% corroded. In active saltwater environments, more frequent checks may be necessary. Leaving a depleted anode on can lead to costly damage to your outdrive.
What are the signs of a failing or depleted anode?
A failing anode will often look heavily pitted, be crumbling, or appear significantly smaller than a new one. Once the anode is more than halfway gone, its ability to protect the metal components of your outdrive is greatly reduced.
Why use a zinc anode kit instead of aluminum?
This kit contains zinc anodes, which are the industry standard for providing cathodic protection in saltwater. Aluminum anodes are typically used for brackish water, while magnesium is reserved for freshwater applications.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
