Mercruiser Driveshaft Support Bearing, older Alpha One Bravo

Thrust bearing MerCruiser Alpha One and Bravo older models

Genuine MerCruiser thrust bearing for older Alpha One and Bravo drives. The thrust bearing supports the drive shaft and is an important part of the smooth and quiet operation of the drivetrain. A worn or damaged thrust bearing often causes excessive 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. It is recommended to use an alignment tool during installation to ensure correct alignment of the support bearing.
