What this video covers
The crew of the wooden sailboat Yabá installs a two-inch bronze through-hull fitting for the engine’s raw-water cooling system.11:08 After initially planning to share a single large through-hull between the watermaker and the engine, the crew decides to keep the systems separate to prevent vacuum issues and potential watermaker damage.8:47 They position a custom-welded stainless steel raw-water filter to allow for a straight hose run, minimizing the use of elbow joints.7:55 Because a two-inch hole saw is unavailable, the crew drills a series of small holes around the perimeter of the marked circle and uses a jigsaw to remove the center plug from the hull planking.13:51 They seal the exposed wood inside the hole with thickened epoxy to prevent rot.20:12 The project also includes priming the newly welded keel plates with epoxy to prevent corrosion and cleaning the metal surfaces with Scotch-Brite before final coating.21:02
