    • A trolling attachment for an outboard engine includes a strap element for securement to the upper section of an engine housing and a plate member having an axial slot extending inwardly from one end for securement to the lower section of an engine housing. A handle rod is extendable slidably through apertures in a flange element projecting perpendicularly from the strap element and in the plate member. A trolling flap is hingedly secured to the lower surface of the plate member and pivotably mounts the lower extremity of the handle rod. A pin is carried by the flange element that is cooperable with the handle rod for releasably locking the handle rod in a selected vertical position. A lower region of the handle rod is rearwardly offset and given a notch which is cooperable with the plate member for releasably locking the trolling flap in its vertical position.
