Troubleshooting & FAQ

Q: How do I confirm this fits my stern drive?

A: This kit is designed for MerCruiser Alpha One Gen 2 and Bravo 1, 2, and 3 stern drives. Please review the "Compatible Engine Models" table and cross-reference your OEM part numbers (e.g., 22-861150T02, 22-861163) to ensure a match.
