I just this boat and the controls are omc. the motor is a 1963 Johnson 75 horse electric, super sea horse. I don't understand how the controls work with the motor. the controls have two handles, one with a red top and one with a black, black on the inside and shorter. no switches and and two black knobs. a idle stop and throttle tension. no electric components. two cables go to the motor and I dont see anything electric on the motor that would be activated by them. any help? I feel lost. I need to know what lever does what. I was told by the previous owner that he could never get reverse to work either. I think that it might have the wrong controls or need adjustment. I just dont get it. thanks.
