The McKenzies are were junk. It is the system I had. The rod would not bend, but the stainless steal screw did. WHAT A PAIN IN THE AAHOLE to replace that screw once bent. Also the rudder arms going to the stocks were underengineered. I must have done around two or three repairs already to each stock. The ones that came on my boat, were junk. I have done extensive modifications to my rudder system and today it is a much better setup.
