Abstract: A universal transducer mounting bracket (10) that may be used to mount a transducer (12) to either a transom (14) or a trolling motor (16). A mounting body (18) broadly comprises a transom attachment (36) for mating to the transom (14), at least one hole (20) through the transom attachment (36) for accepting one or more fasteners therethrough in order to secure the bracket (10) to the transom (14), and an arcuate top wall (22) for mating to the trolling motor (16). The mounting body (18) preferably further includes two side walls (26) and a bottom wall (30) forming the transom attachment (36) for rigidly securing the bracket (10) to the transom (14). The transom attachment (36) may be defined by the walls (22,26,30,34) forming a perimeter around an opening, thereby making the bracket (10) hollow.
