A wake control device for a boat, including a mounting member pivotally securable to the boat aft for pivoting about a first axis substantially transverse to the boat aft, a rudder member secured to the mounting member for pivoting about a second axis substantially perpendicular to the first axis, a drive selectively controlling the pivotal position of the mounting member about the first axis, and a fin extending laterally relative to the rudder member. Such a wake control device, with or without pivoting about the second axis, may also be secured directly to an outboard drive as well. A control manually operable by a wake boarder while being towed remotely controls the pivotal position controlling drive.
