Re: Modify 1964 Evinrude 28hp 2 cylinder?
The motor doesn't really care what control cables are hooked up to it. The cables are set by the control box, not the motor. I am pretty sure you can put the throttle clip and the shift pin on a later style cable. You would need to make sure you have the larger style cable anchors (you may already have them depending on what cables you're currently using) on the motor to accommodate the plastic trunion nut on the cables.
So, the question is, what control box are you attempting to use?
