Frequently Asked Questions

Does universal mean it fits every Alpha and Bravo drive?
No. Mercury's catalog specifically lists 2014 and newer Bravo drives. Confirm other applications and installation requirements by serial number.

Is this the yellow 1,000 mA outboard module?
No. This kit uses the red-label sterndrive controller; the yellow outboard module is a different part.
