I just bought an '85 Evinrude 20hp, E20ELCOS, that came with an OMC single lever control box with the red coupling to the motor. There were no throttle of shift controls in this box. They were in another two lever box that had connections to the outside of the motor, the connector to the throttle was broken. I would like to have the contols all in the OMC contol box. Is this possible? If so what connectors do I need to get this setup to work. I assume new shift and throttle cables are needed but where do I get the connectors to the motor?
