Mercury 805101T – Rear Propeller Thrust Hub | Bravo Three Dual-Prop Sterndrive
Part Number: 805101T
Brand: Mercury Marine
Type: Rear Propeller Thrust Hub
Position: Rear Propeller Shaft
System: Bravo Three Dual-Prop Sterndrive (and selected related applications)
GTIN: 745061060937
Genuine Mercury Marine OEM rear propeller thrust hub for selected Bravo Three dual-prop sterndrive assemblies. The 805101T installs on the rear propeller shaft, between the gearcase hardware and the rear propeller, providing the correct thrust surface for proper propeller seating and retention. This is the rear position thrust hub — do not interchange with the front thrust hub (805100T), which is a separate, distinct part used in the same assembly.
Compatible Applications
- MerCruiser Bravo Three dual-prop sterndrive – rear propeller position
- Selected Bravo Four S propeller assemblies – confirm drive and propeller configuration
- Selected Zeus propeller-related assemblies – confirm exact configuration
Fitment Notice: Confirm the exact drive model, propeller configuration, and diagram position before ordering. 805101T is specifically the rear propeller thrust hub. The front thrust hub in the same assembly is a separate part (805100T) and the two are not interchangeable. Verify against the applicable Mercury parts diagram for your drive.
Diagram Position
In Bravo Three propeller-shaft assembly diagrams, 805101T is identified at the rear propeller position — installed between the gearcase/propeller hardware and the rear propeller. The front thrust hub (805100T) appears at the forward propeller position in the same diagram.
When to Replace
- Hub is worn, distorted, cracked, or heavily corroded
- Hub was damaged during propeller removal
- Propeller will not seat correctly on the shaft
- Any time the rear propeller is removed for inspection or service
Installation Notes
- Remove the rear propeller and inspect the propeller shaft, splines, and thrust surfaces before installation
- Inspect all propeller hardware for wear or damage at the same time
- Install 805101T in the correct rear propeller position only
- Torque the propeller hardware per the applicable Mercury service procedure

Parts Desk Insights
The single most important detail with 805101T is rear propeller position. On Bravo Three-style dual-prop systems, the front and rear thrust hubs are different parts — ordering the wrong one is the most common mistake. Always confirm which position needs replacement before ordering. If both are being replaced at the same time, 805100T (front) and 805101T (rear) are ordered separately. Anytime a propeller is removed for service, it’s good practice to inspect the thrust hub for wear before reinstalling.
