I have a 1984 Mercury 50hp 4cyl outboard. The Plate throttle actuator broke and ordered a new one. My problem is the manuals I have do not mention this part or how to adjust it. The adjustment screw on the broken piece is missing, along with the ear that it screws into. I have the new parts but no way to know how to set the screw adjustment. I've searched the web and found nothing. Does anyone know how to adjust this actuator or where to find any documentation on how to adjust it?? Many thanks.
