Saturday evening after a few hours on the water and everything was fine, we turned the engine off. After about 30 mins we attempted to start it. Just turned the key 2 times and gave up. NOTHING from the starter and the starter was HOT! Got a tow home.
Sunday we replaced the starter and had same result. Nothing from the starter. Attempted to jump starter by crossing the slave solenoid and we burned up the (yellow/red) wire going to the starter.
We replaced the wire and replaced the slave solenoid today. When we turned the key the yellow/red wire burned up again.

The yellow/red wire should be the ignition wire….

We are STUMPED as to what to do now. What do we check? What went bad to cause the original no starter problem? What’s wrong now that the wire keeps burning up?

Please give me your thoughts. I have a good service manual but the wiring is not the same. Black Red wires. Imagine that! 🤣IMG_2597.jpegIMG_2596.jpegIMG_2594.jpegIMG_2593.jpegIMG_2595.jpegIMG_2592.jpeg
