Unfortunately I think Dave is probably correct. If you release the wheel, does the boat travel in a straight line or does it slowly turn? If the boat does not travel in a straight line (to be certain with the engine in neutral) then the rudder aerofoils are not symmetrical. The effect is analagous to the mode of operation of "trim tab" self steering.
