What this video covers
The crew of the Open 66 sailboat NV is performing a full engine repower while on the hard in northern Borneo.▶ 0:06 To accommodate a more powerful engine, they are installing a new ZF gearbox and sail drive.▶ 0:10 Because the engine room space is too tight to install the sail drive as a single unit, the crew splits the leg from the upper gearbox to join them inside the hull.▶ 3:27 Timo rigs a support line to a new pad eye on the engine room ceiling to bear the weight of the unit, protecting the diaphragm and seals during the installation.▶ 3:13 After discovering the hull opening was too small for the new leg, he trims the aperture with a multi-tool, then fares and re-laminates the opening.▶ 5:55 The ZF gearbox features a double-sealed diaphragm, a water-in-oil humidity sensor, and a service tube for internal oil extraction.▶ 10:26 The installation concludes with the gearbox bolted in a star pattern to ensure even compression on the diaphragm.▶ 7:12
