I have a 97' mariner/mercury 25hp 2-stroke and I have a brand new cables (negtive and postive wire). I'm trying to hook everything up and push the start button then won't start. I checked the starter gear with spring and it went up to a flywheel by hand. What's yellow wire coming from bottom of the starter??? Is suppose to be a postive wire hook up to a starter? All I see a yellow wire hook up to a starter? Do u have any pictures on side of the motor so I can get a idea of it. I tried hook up everything and clean the wires ......nothing.....do I did something wrong? Need help thanks........Brett....u know?
