Abstract
A raising and lowering aid for trolling motors which includes a pair of torsion springs, each having one end fixed with respect to the deck fixture of the trolling motor bracket and the opposite end engaging a pair of connector bars which are pivotally mounted to the deck fixture at one end and slidably mounted at the opposite end to conventional, parallel pivoting primary arms, also pivotally supported by the mount shoe. The springs are adjustable with respect to the deck fixture in order to adjust the spring tension and the raising and lowering aid operates to assist the user in retracting the trolling motor from the water on the bracket and lowering the trolling motor into the water from the bracket during operation.
