ABSTRACT:
A trolling motor bracket having a pivoting "breakaway" feature to protect the shaft of a trolling motor, and a shaft rotating feature, which bracket is characterized by a shaft bracket having a split housing and designed to adjustably receive the trolling motor shaft; a bracket hinge pivotally attached to the shaft bracket, and breakaway pins for friction engagement with a cooperating slot in the shaft bracket to facilitate downward pivoting of the shaft bracket and trolling motor with respect to the bracket hinge when the trolling motor encounters an underwater obstacle; and a support bracket mounted on a conventional trolling motor lift bracket attached to the boat, and attached to the bracket hinge. The trolling motor can be pivotally adjusted with respect to the bow of the boat by operation of the bracket hinge, and the pressure required to effect downward pivoting of the shaft bracket and trolling motor shaft on the bracket hinge can be controlled by adjusting the breakaway pins. In a preferred embodiment of the invention a specially designed insert is provided in the shaft bracket to effect a positive and adjustable engagement of the trolling motor shaft by the shaft bracket.
