What this video covers

The crew of the yacht Catalpa performs maintenance on their Max-Prop three-blade propeller and hull while hauled out at a boatyard in Puerto Peñasco, Mexico.0:26 Due to missing anodes, the propeller shows significant electrolysis damage; the crew cleans, degreases, and wire-brushes the unit before reassembling it using a service kit from PYI.4:16 They delay greasing the internal housing until just before relaunch to prevent the lubricant from melting in the extreme local heat.4:59 Additionally, the crew repairs hull blisters by grinding out damaged areas, filling them with thickened epoxy resin, and applying a barrier coat.8:56 They also acquire a donated 9kVA generator, which they plan to troubleshoot for fuel system issues and integrate into the boat’s 110V electrical system using a Victron converter.11:19 The project is complicated by the difficulty of sourcing specific materials like silica and epoxy locally, requiring the crew to rely on friends to transport supplies from the United States.9:23
