Abstract: A universal clamp assembly for remotely placing a motor flushing device over the water inlet ports of an outdrive of a marine motor from either above (twelve o'clock position), below (six o'clock position), to the right (three o'clock position), or to the left (nine o'clock position) of the motor to direct clean, fresh, water through the inlet ports to flush the interior of the motor. In a second embodiment of the universal clamp assembly as depicted in FIG. 3, the universal clamp assembly comprises a first, generally T-shaped, clamp member including a foundation for securing a motor flushing device thereto in a first orientation; and a second, generally Y-shaped, clamp member including a foundation for alternatively securing a motor flushing device thereto in a second orientation. When assembled, the foundation of the first clamp member is in a plane generally perpendicular with the foundation of the second clamp member.
