ABSTRACT:
A yieldable protective mounting mechanism for trolling motors incorporates a mounting base that is fixed to the deck structure or the stern structure of a small boat such as is typically used for recreational activities such as fishing. A motor support element is pivotally connected by hinge structure to the base and is continuously urged by tension springs to an operating position where the trolling motor is positioned for its normal operation. In the event the trolling motor should strike a submerged object, the tension springs permit pivotal movement of the trolling motor to prevent it from being overstressed and bent or otherwise damaged. The tension springs also provide a braking force to the boat causing the boat to come to a complete stop from its slow movement so that the motor can be reversed and the boat and trolling motor backed clear of the submerged object. This yieldable protective trolling motor mount may be positioned at the bow or stern of a fishing boat as is desired, there being only slight modification in structure but essentially identical function in use.
