🔌 Function

Secures the forward propeller to the IPS propeller shaft at the specified torque.

⚠️ Common Signs of Failure

• Propeller movement on the shaft
• Corrosion or galling
• Nut will not retain the specified torque
• Damage caused by incorrect removal tooling

🛠️ Service Notes

• Assemble the thrust washer, cone and any spacers in the order the manual gives onto a clean, undamaged thread — the propeller is clamped by the whole assembly, not held by the nut alone
• Tighten to the figure given in the workshop manual for your drive; a nut merely nipped up lets the propeller work on the shaft and ruins the hub and the taper
• Fit a new locking device where one is used — a lock or tab washer bent onto the flats, or a new split pin — and never reuse one that has already been bent
• Renew the nut if the thread is stretched, galled or corroded, or if the locking tabs or their seats are damaged; a corroded nut is also the reason a propeller will not come off next time
• Check the nut and its locking after the first run and at every haul-out — a slack propeller nut is a common cause of vibration and of lost propellers
