🔌 Function

Clamps the propeller onto its shaft and holds it there against thrust, torque reversals and vibration.

⚠️ Common Signs of Failure

• Propeller loose on the shaft, or a knock felt through the hull when shifting
• Thread damage or pick-up when the nut is removed
• Locking feature worn so the nut no longer stays put
• Corrosion or seizure between nut and shaft
• Nut faces rounded from being turned with the wrong tool

🛠️ Service Notes

• Propeller nuts are torque critical - tighten to the manual figure and fit the locking arrangement exactly as designed
• Renew the locking components at the same time rather than reusing them
• Clean and check the shaft threads before fitting, as damaged threads will not hold the correct clamp load
