What’s in the Box

  • 1 x Transom Shield Zinc Anode (Replaces Volvo 3588745/3588770)
  • 1 x Cavitation Plate Zinc Anode (Replaces Volvo 3588746/3588748/3863206)
  • Mounting Hardware

Installation Notes

  1. Disconnect the vessel's battery before starting installation to prevent electrical hazards.
  2. Unbolt and remove the old, depleted anodes from the outdrive's transom shield and cavitation plate.
  3. Thoroughly clean the mounting surfaces on the outdrive, ensuring they are free of corrosion, paint, and sealant.
  4. Position the new zinc anodes onto the cleaned surfaces.
  5. Ensure firm, direct metal-to-metal contact between the anode and the outdrive for proper electrical conductivity.
  6. Securely fasten the anodes using the provided mounting hardware. Do not over-tighten.
  7. Never paint anodes or the mounting surfaces, as this will insulate them and prevent them from working.

Troubleshooting & FAQ

How do I know if this anode kit fits my Volvo Penta outdrive?

This kit is a confirmed fit for all Volvo Penta DPH and DPR series outdrives. Always compare the product images to your existing anodes to ensure a correct match before installation.

What is the difference between this zinc anode kit and an aluminum one?

Zinc anodes, like those in this kit, are specifically formulated for optimal corrosion protection in saltwater. For use in brackish or fresh water, an aluminum anode kit is recommended.

How often should these anodes be replaced?

Anodes should be inspected during regular maintenance (at least every 6 months) and replaced when they are approximately 50% consumed. The rate of corrosion depends on factors like water salinity, temperature, and nearby electrical currents.

What are the signs that my anodes need replacement?

Visible signs of failure include rapid or uneven corrosion, or significant pitting on the drive components themselves. Anodes develop a white, chalky appearance as they corrode, which is normal. However, if the anode is nearly gone or the drive's metal is corroding, replace the anode immediately.

What’s the difference between OEM and aftermarket parts?

This listing is for an aftermarket replacement part, not an original equipment manufacturer (OEM) component. It is built to meet or exceed OEM-level specifications using comparable high-quality materials and is manufactured in an ISO 9002 certified facility with batch-inspections for quality assurance.

How much is shipping and how fast will it arrive?

We ship worldwide quickly, with typical transit times of 5–15 days for most destinations. Standard shipping is free. If available for your location, expedited shipping options and their costs will be presented at checkout.

What is the warranty and return policy?

This product is covered by a 1-year warranty against manufacturing defects under normal operating conditions. If you encounter an issue, please contact our support team with your order details. Returns are accepted within our standard return window for unused items in their original condition. See our full policy page or contact us for instructions.
