Abstract: An apparatus for continuous adjustment of the direction of the rudder position of an outboard motor powered boat while trolling and permitting the fisherman's hands to be free as the boat follows the desired course. A tubular sleeve (24) slides over a rod (18) which is pivotally attached to a mounting bracket (10) affixed to the side of the boat. The sleeve (24) includes a pin (26) for engaging a hole (48) in a pilot bracket (38) attached to the outboard motor (40) or the tiller (52) of the boat, and a rotatable mechanism (34) to lock the sleeve to the rod. Sliding the sleeve (24) along the rod (18) changes the rudder position of the boat, the position being fixed when the sleeve (24) is locked to the rod (18). Manual operation is restored by lifting the rod (18) to disengage the pin (26) from the pilot bracket (38).
