What this video covers
After a feathering Autoprop fails at sea during a passage to Indonesia, the crew of the 45-ft catamaran Nandji - Frothlyfe returns to Pangkor Marina, Malaysia, for repairs.0:19 Underwater inspection reveals the left-hand threaded locking nut on the propeller hub failed, causing the blades to loosen.6:59 The crew sources a replacement hub, internal bearings, and a fixed-blade spare prop from a machine shop in Ipoh.9:15 Because the fixed-blade spare lacks a locking pin hole, the host uses a pneumatic drill to modify the nut and shaft for a secure fit.13:12 After rebuilding the original Autoprop with new internal components and verifying the locking nut threads fully into the new hub, the crew installs the unit and conducts sea trials at full RPM.14:15 The rebuilt propeller operates without vibration or noise, confirming the repair.17:06 Proper thread engagement and secure locking mechanisms are critical to preventing catastrophic failure of feathering propeller components under load.
