What this video covers
Adam and Luke attempt to resolve a persistent whirring noise in their boat's drivetrain by replacing a damaged coupling between the gearbox and the drive leg.▶ 0:28 After failing to remove the old coupling with a puller, they consult a local contact who confirms the rubber inserts are degraded and the inner steel casing is likely striking the frame.▶ 5:54 The pair orders a replacement coupling from the UK and sources stainless steel bolts from a local supplier, Ajax Fasteners, to complete the installation.▶ 6:53 During the repair, they inadvertently ground the boat sideways on a sandbank at a river mouth while waiting for the tide, risking hull damage from the swell.▶ 14:26 Once refloated, they align the new coupling using a feeler gauge and a makeshift brass nut spacer, achieving a tolerance of 0.018, which falls within the manufacturer's specified range of 0.008 to 0.025.▶ 21:33 While the whirring noise is eliminated, the engine test reveals a new exhaust leak from a hole in the exhaust elbow and a misaligned gear linkage.▶ 26:58
