3InstallationMounting the TransducerIn-hull InstallationThe 010-10224-00 transducer is designed to be mounted inside afiberglass hull. The standard plastic transom mount transducer can also bemounted in this fashion using this method. If using a temperature sensingtransducer, the temperature displayed will reflect the hull temperature.Selecting a Location1. The location has to be solid fiberglass, devoid of any air bubbles,laminates, fillers or dead air space. The location needs to be in an areaof clean water at all speeds. Do not place the transducer over anystrakes or behind any obstruction on the hull that would createturbulence at speed.Many modern hulls have a prelocated pocket for In-hull transducerinstallation. If you are unsure if your hull is equipped with a prelocatedpocket, contact your hull manufacturer.Testing the LocationPlace the transducer in the water, pointed directly at the bottom and setunit for optimum performance. Place the transducer in the test device asshow on the side bar. If the sonar performance is significantlydegraded, another location will need to be tested.Installing the Transducer1. Lightly sand the surface of the hull and face of the transducer with 400grit wet or dry sandpaper.2. Build a dam using strip caulk about 1/4” tall. Pour about 1/8” of twopart, slow cure epoxy in the dam. Place the transducer in the epoxy,turning the transducer to work out any air bubbles.3. Weight the transducer in place and allow to cure for 24 hours.Strip Caulk orRTV Sealer DamSlow cure twopart epoxyApply twistingmotion to eliminateany trapped airbubblesWeight transducer in placefor at least 24 hoursTesting the LocationPVC Pipeor a CanStrip Caulk orRTV SealerHull SurfaceWeighttransducer tohold it in placeInstalling the TransducerFill Pipe or Canwith water or alight mineral oil
