Patrick, I just did a rewire on mine. I did all of the main power to switch, switch to 3 panels and the entire engine.
I did not wire the engine as convention would dictate. Rather than have 2 sets of wires going aft for the main panel and the engine, I took a #6 wire to the panel and from there 18" away a #10 to the engine panel for it's power. Doing so really cleaned up a lot of the wiring.
I did change some of the color coding
( OK to cringe Neil) to the engine as I was using "harsh environment bundled cable" for a harness (5 wires) for the power to the engine. I have an ammeter wired in at the "engine" panel I have below which eliminated a 30' charging run that's now less than 3'. Everything works better and I have more voltage available everywhere due to shortened runs, a good thing to consider when rewiring.
I figure the engine is part of the boat so why not include it with the boats wiring system instead of a separate one. All I really did was pick up my engine power from a source that was close and needed to be in the same area~~food for thought. It's my boat and I don't like the "Universal" wiring kits that were supplied due to the "plug".
I did make an engine wiring diagram for the boat files
.
In the years since the boat was built many things were added and dropped etc, so things can get to be a mess. Take a good look at what you have and what you want, a bit of thought can really make things a lot simpler.
