I've decided I need to make a new harness for my '74 inline 6. Pretty much all the wires are crumbling and green. I'm not going to spend ~$200 for a new one from ebay. I'll need something to cover the bundle of wires going from the outboard to the boat - an ideas? I need something that looks ok and would protect it from the elements. Normal split loom would just fill with water and doesn't look very good...
