INSTALL THE OVERFLOW/VENT FITTING
Select a location on the boat’s side or transom for the stainlesssteel through-hull fitting that serves as the vent/overflow for the ballast bag. The fitting should be located higher than the water level in the bag when it is full. Cut and chamfer a 11/16-inch hole in the desired location. Bed the hole on both sides with the supplied marine sealant/adhesive and insert the fitting from the outside, then tighten and torque the fitting nut on the inside to ensure a watertight fit. Wipe away any excess sealant.
