I have a two part project going and have a few questions. I rencently purchased a 1993 Johnson 200 with controls for my boat. At the same time I am working on a project boat with my father. He purchased a 1976 Johnson 85 but his controls are a little rough. Will the controls from my 1993 200 work for his 1976 85? By controls I mean gear box and igniton only (no gauges). Also if control cables (throttle/shifter) are replaced do you use the new or older style. Thanks in advance.
