ABSTRACT:
A trolling attachment for motor boats comprises pivotal trolling flaps for securement to the transom of a boat so that the flaps may be lowered into and raised from the water as required. The flap are carried on a rectangular box-section tube with leaf springs disposed against the tube to provide resilient frictional resistance to movement of the flaps and positive location and retention of the flaps in the raised and lowered positions by engagement of the springs against adjacent surfaces of the tube respectively.
