Hi, I'm hoping someone may be able to help, please? We have a chico 40 Blue horizons, and the steering is seized. I can not identify the system. It's not Lewmar, Edison, Whitlock, or Yachting Specialities. It's a 1984 model. The seizure it on the shaft bearings, but I can't get it apart and can't find a diagram. Any assistance would be greatly appreciated. Thanks Tim.
