Inspection and Replacement
Inspect the anodes during routine service and seasonal haul-out. Replace anodes when approximately half of the material has been consumed, when corrosion is advanced, or when the anode no longer maintains sound contact with clean bare metal. Replacing the kit as a set helps keep protection balanced across the drive assembly.
Installation Notes
- Mount anodes to clean, bare metal surfaces and do not paint the anodes.
- Ensure proper electrical contact at each mounting point.
- Use the current service manual for hardware sequence and torque specifications.
- Confirm the correct kit for the drive serial number before installation.
Technical FAQ
Does 818298Q1 fit every Alpha One sterndrive?
No. It is listed for selected Alpha One Gen I and Gen II applications. Confirm the drive serial number and parts diagram because anode kits can differ by generation.
What positions does this kit protect?
The kit is intended to replace the applicable factory anodes on the gearcase, trim tab, and transom assembly. Verify the exact positions and contents for the installed drive.
Can I mix old and new anodes?
For balanced corrosion protection, replace the applicable anodes together and keep each mounting surface clean and electrically continuous.
Should I choose aluminum or zinc?
Use the material specified for your boat’s water conditions and the applicable Mercury or service recommendation. Confirm the correct material and drive application before ordering.

Parts Desk Insights
Best use: Use 818298Q1 when the applicable MerCruiser Alpha One diagram specifies a complete aluminum anode kit for the gearcase, trim tab, and transom positions.
Most common mistake: Ordering an Alpha One kit without checking the drive generation or serial number. Gen I and Gen II kits can look similar while using different anode arrangements.
Fitment and sizing: Match the complete 818298Q1 number, aluminum material, Alpha One generation, drive serial number, and current parts diagram before ordering.
