I have a '63 75 hp johnny that refuses to start. I was cranking it for about ten minutes but could not get it to start. I left it alone for a while and when I went back all I heard was a weird click. But it did not sound like it was coming from the starter, or from anywhere on the motor for that matter. There is a box that sits near the motor, could it be coming from there? I am new to boating so even my diagnostic skills are pretty bad.
