  • Tie a length of monofilament to the eye and place it into the already-cut hole in the hull of the boat.
  • Apply caulking to the flange of the fitting, and pull the fitting through the hole and against the hull from inside the boat.
  • Thread the mono-filament through the locknut or seacock.
  • With the fitting pulled firmly against the hull the locknut or the seacock may be screwed onto the fitting.
