What this video covers

Adam and Luke of the Sailing Brothers attempt to diagnose a persistent knocking noise in their engine transmission while cruising near Nadi, Fiji.3:21 After observing significant rhythmic movement in the engine block, they spend four and a half hours performing a precision alignment of the engine shaft using feeler gauges, successfully reducing the tolerance to 0.013 millimeters.9:49 Despite the alignment, the knocking persists, leading the crew to conclude the issue lies within the gearbox.12:44 To access the unit, they anchor in shallow water off a beach and remove the drive leg by jumping overboard to unbolt the assembly while the boat floats in approximately 1.5 meters of water.17:50 Upon disassembly, they discover the coupling is seized and in poor condition, preventing further progress.22:55 The crew struggles with rounded bolt heads and seized components throughout the removal process, ultimately failing to extract the gearbox or identify the specific source of the mechanical failure.15:50
