A method for mounting a transducer in a boat hull is disclosed where the transducer has a frusto-conical outer end portion adjacent an end which is to be mounted flush with the boat hull. Initially, a member is positioned at a predetermined location in the boat hull mold, which member includes an upwardly converging frusto-conical surface. The boat hull is then molded around the member and the molded boat hull removed from the mold. The transducer is then attached to the portion of the boat hull which was molded about the member. In one embodiment, the member is a plug and the plug is mounted to the hull mold so that the removing of the boat hull from the hull mold also includes the removing of the boat hull from the member. The plug can have a thickness greater than the boat hull, or less than the boat hull in which case a subsequent cylindrical hole is drilled in order to attach the transducer. In an alternative embodiment, the member is a collar having a cavity therein which receives the transducer. During the molding step, the collar is bonded to the boat hull so that the transducer is attached to the collar and hence to the boat hull after removal of the boat hull from the hull mold. If desired, an alignment element can also be provided on the transducer and a mating element provided in the boat hull.
