The present invention discloses a boat motor trolling attachment for use in conjunction with a boat motor and propeller to achieve effective trolling speeds. The boat motor trolling attachment includes a frame, defining an opening, and attached to a mounting bracket which is secured to the boat motor. Two springs are attached between the frame and the mounting bracket so as to bias the frame into a trolling position wherein the frame is disposed in a plane perpendicular to an axis defined by the propeller. Four control members are disposed horizontally across the opening and rotatably fixed to the frame so that a outflow of water impinging on the control members when the boat motor is in a forward gear automatically causes the control members to rotate in the frame so as to substantially close off the opening and form a continuous surface. The outflow of water generated by the propeller acts on the continuous surface and is transmitted thereby to the boat so as to resist forward motion of the boat. When the boat motor is in a reverse gear, the control members automatically rotate to allow a inflow of water to be generated by the propeller thereby facilitating control and maneuverability of the boat in reverse. At high forward speeds, the outflow of water generated by the propeller overcomes the bias imposed on the frame by the springs and automatically moves the frame to an inoperative position wherein the frame is disposed in a plane substantially parallel to the axis defined by the propeller.

1. A boat motor trolling attachment suitable for use in conjunction with a boat and a boat motor, the boat motor having a propeller and including a forward gear and a reverse gear, comprising:(a) a mounting bracket configured for attachment to the boat motor; (b) a frame defining an opening, said frame depending from said mounting bracket; (c) at least one resilient member operably interconnected between said mounting bracket and said frame, said at least one resilient member biasing said frame into a trolling position; and (d) at least one control member disposed across said opening, said at least one control member transmitting a portion of a force exerted by the propeller to the boat so as to at least partially counteract forward travel and reduce speed of the boat when the boat motor is in the forward gear, and said at least one control member permitting an inflow of water through said opening to the propeller so as to facilitate maneuverability and responsiveness of the boat when the boat motor is in the reverse gear.
