U-joints
NOTE: Bravo Models - The crosses and the bearings on the sterndrive U-joint will need
to be lubricated through the grease fittings. The sterndrive unit must be removed to grease
these fittings.
1. Remove the sterndrive unit; refer to the appropriate Mercury MerCruiser Sterndrive
Service Manual for sterndrive unit removal and installation.
2. Apply U-joint And Gimbal Bearing Grease (Except on Bravo X Drives - use Exxon Unirex
EP2 Grease [Obtain Locally] ) from a typical hand-operated grease gun until a small
amount of grease begins to push out.
3. Lubricate the U-joint shaft splines using Engine Coupler Spline Grease.
