Installation Notes
- Disconnect the boat's battery before starting work.
- Remove the old, corroded anodes from the sterndrive unit. Note the position of each component.
- Thoroughly clean the mounting surfaces on the drive. A wire brush or sandpaper is effective for removing any residue or oxidation.
- Ensure the mounting surface is bare metal; do not apply paint between the anode and the drive.
- Install the new anodes onto the corresponding clean surfaces using the new hardware provided in the kit.
- Tighten all fasteners to the manufacturer's recommended torque specifications to ensure a solid electrical connection.
- Once all anodes are installed, you may reconnect the battery.
Troubleshooting & FAQ
Why choose an aluminum anode kit over zinc or magnesium?
Aluminum anodes are the most versatile choice, offering excellent protection in fresh, brackish, and saltwater. Zinc is only effective in saltwater, and magnesium is designed exclusively for freshwater, where it can over-protect and cause paint blistering. This aluminum kit is the ideal universal solution.
How can I be certain this kit fits my MerCruiser Bravo drive?
This kit is specifically for Bravo II drives (1988+) and Bravo III drives from 1995–2002. The key is to check your drive's serial number. It fits Bravo II S/N 0B664190 and up, and Bravo III S/N 0F345868 to 0M179451. If you have a 2003 or newer Bravo III, you need a different kit (part number 888761Q04).
How often should I inspect and replace my drive anodes?
Anodes should be inspected at least once a season or every 50-60 hours of use. A common rule is to replace them when they appear to be 50% corroded or dissolved. Regular inspection is critical for protecting your expensive sterndrive components.
What are the signs my old anodes have failed?
Visible signs include the anodes being heavily pitted, crumbling, or almost completely gone. You might also notice new signs of galvanic corrosion (pitting, bubbling paint, or white powdery residue) on the drive unit itself, which indicates the anodes are no longer providing protection.
Can I use this kit on a Bravo I or a post-2002 Bravo III drive?
No. This kit is not correct for Bravo I drives. For Bravo III drives made in 2003 or later, you must use kit 888761Q04. Using the wrong anodes can result in inadequate protection and damage to your drive.
Is the hardware included for all anode components?
Yes, this is a complete 4-piece anode kit that includes all required mounting fasteners to install the flat trim tab anode, driveshaft plate anode, and both lift ram anodes.

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.
