Qué cubre este vídeo
The crew of the Lagoon 450 *Parlay Revival* diagnoses a persistent knocking sound in their sail drive while cruising in New Zealand.0:31 After eliminating the clutch assembly as the source of the noise, they perform an underwater removal of the folding propeller to isolate the fault.1:11 Running the engine without the prop confirms the mechanical failure originates within the lower unit of the sail drive.9:58 The crew hauls the boat out at Opua to inspect the leg, where they discover a broken gear tooth.16:38 They attempt to replace the damaged SD50 sail drive with a donated SD60 unit, but find the two models incompatible due to significant differences in spline count, gear design, and mounting dimensions.17:39 The repair requires either machining the existing shaft or sourcing a direct replacement for the SD50. The crew documents the process of troubleshooting mechanical drive issues, underwater propeller maintenance, and the complexities of retrofitting different sail drive models.
