I have a broken powershift 2 remote control for my 74 Johnson 50hp outboard. I was wondering if it is possible to replace my old shifter with a Johnson or Evinrude two handle shifter (shipmaster or simplex). My wires to the powershift no longer have the red connectors (long replaced by former owners by wire splices). So would wiring a toggle switch for choke and a keyed switch for starter work as a replacement?
