Hmmmm, I don't know if this was a double post or not. Seems as though I saw the identical thread yesterday answered by some very knowledgeable individuals. In a nut shell, what they stated was there is wire and then there is wire for a marine application. And, of course, the marine application costs more. LOL. If your going to be using the vessel in salt water, it's best to get the marine wire. If freshwater, regular wire from an auto parts store, or a place like Walmarts or bulk wire from Home Depot/Lowe's or similar stores. Ac is different from DC, so you may need a heavier wire to carry the current without loss. When I rewired my boats, i used 14 gauge as the smallest, and ran 10 gauge for a cigarette lighter. Won't say that's right, but its what I did. I also got some plastic wire looms from an auto parts store and enclosed the wires in that. They are still a mess, but it is now an out-of-sight mess. Also, there are standards as to what colored wire is to be used for various implements, ie; the amp meter, Tilt and Trim, Bilge pump... maybe a search on the web is in order. I also purchased a fuse panel from Bass Pro. They have them from around $20.00 to $50.00, depending upon your tase. The main thing is your connections need to be close to perfect, or as close as you can get them. That's where corrosion and moisture will get into the plastic covering. Other than that, have fun.
