Abstract: A device is provided for mounting an outboard motor on the transom of a boat which can be rotated about a horizontal axis to lift the motor out of the water. One embodiment of the device includes two sleeves with an inner sleeve rotatably disposed in an outer sleeve and an outer sleeve is secured at one end to a plate member adapted to be clamped by the conventional inverted U-shaped clamp provided with commercial outboard motors. A second embodiment employs only one sleeve having an annular flange on one end and a plate assembly on its opposite end. The device is mounted on the transom or in a well with its center line of rotation in a horizontal or near horizontal plane. The outboard motor is attached to the device with the center of gravity of the motor on or near the center line of rotation to facilitate rotation of the motor to a lift position out of the water.
