Mercruiser Driveshaft Support Bearing, newer Alpha One Bravo

Thrust bearing MerCruiser Alpha One Gen II and Bravo newer models

Genuine MerCruiser thrust bearing for newer Alpha One Gen II and Bravo I, II and III drives. The thrust bearing supports the drive shaft and is a key component in the smooth and quiet operation of the drivetrain. A worn or damaged thrust bearing often causes noise and can lead to more serious damage if not replaced in a timely manner.

The bearing is supplied with a grease nipple plug, as this model has permanent grease. An alignment tool is recommended for installation to ensure the new thrust bearing is correctly aligned.
