A: This fitting is designed for MerCruiser Alpha One Gen 2 (1998+) and all Bravo sterndrives. Please verify your model against the "Compatible Engine Models" table. It replaces OEM part numbers 22-861150T02, 22-861150A2, and others listed in the cross-reference table.

Q: What are the signs that my gear lube fitting needs replacement?
