Dan and Kika install multiple bilge pumps and reinforced polymer through-hull fittings to finalize the hull integrity of their boat during a refit. They select Whale and Johnson bilge pumps featuring detachable electronics, serviceable impellers, and integrated float switches for maintenance accessibility.1:12 To install the through-hulls, they use a specialized hole saw with a spring-loaded pin mechanism that ejects the fiberglass core plug, preventing the need for manual removal.8:23 After measuring and cutting the through-hulls to fit the variable hull thickness, they seal the fittings to ensure a watertight finish.13:23 The crew then permanently seals a temporary drainage hole in the cockpit bilge with epoxy and fiberglass.19:59 To verify the system, they perform a controlled flood test in the cockpit locker, confirming the pump clears the water in six minutes.30:38 These installations complete the hull sealing process, rendering the vessel theoretically ready for launch.
