What the Carrier Assembly Does

The bearing carrier is a critical internal component of the sterndrive gearcase.

Its functions include:

• Supporting the propeller shaft bearings

• Keeping the prop shaft properly aligned inside the gearcase

• Holding oil seals and internal components in position

• Allowing the prop shaft to rotate smoothly under load

Without a properly functioning carrier assembly, the prop shaft can develop excess play, seal leaks, or gear damage.

---

Typical Service Situations

The carrier assembly is usually replaced during:

• Lower unit rebuilds

• Prop shaft bearing failures

• Gearcase damage from impact or water intrusion

Removal normally requires a special bearing carrier puller tool due to corrosion and tight fit in the gear housing.

Fitment Tip:
Always confirm compatibility using the sterndrive serial number. Alpha drives have multiple carrier designs depending on gear ratio, model year, and drive generation.
