I converted my Sea King 15 to electric start by mount the solenoid on the side of the motor with bracket part numbers121562 and 311218. Its a 2 piece bracket. The turned the stop button into the start button. I took out the idle screw so I could kill it with the throttle like a 5.5 or 7.5. You can remove the hardware on your motor where the old plug socket is and mount your start button there. You will have to also drill a small hole in your lower pan for your battery cables.
