Abstract
A trolling plate assembly for mounting on the motor of a small boat. The trolling plate assembly has a mounting bracket comprised of a flat plate with flanges extending upwardly from, and perpendicular to, the longitudinal edges of the plate. A fixed axle extends between the flanges. A movable locking rod extends between the flanges forward of the axle and parallel thereto. An outer, frame plate has cam ears located at one end thereof. The cam ears are pivotally attached to the axle. A trigger plate is positioned inwardly of the frame plate and has cam ears pivotally attached to the axle. The locking rod is urged by spring means toward the axle and into compressive contact with the outer surfaces of the cam ears of the frame and trigger plates. In a non-trolling position, the locking rod is seated in non-trolling recesses located on the outer surface of the cam ears of the frame plate to thereby lock the frame plate in a substantially horizontal position. When the motor is placed into reverse, the boat backs up and the pressure of the water acting against the trigger plate causes the cam ears of the trigger plate to rotate against the rod and move it out of locking engagement with …
