Abstract
A spring-biased mechanism that connects to and cooperates with a trolling motor mount is provided to partially counterbalance the weight of the trolling motor as it pivoted from an intermediate position into operating position and back again, thereby making easier the effort normally exerted by the operator to lower the trolling motor into the water, as well as to raise it from the water, which mechanism includes a foot element that pivotally attaches at one end to the trolling motor mount, a linear-acting spring unit having one end pivotally attached to one end of the foot element and means that pivotally connect the opposite end of the foot element to a portion of the spring unit.
