Rewiring Boat
 

Hello,
So I am in the process (Or very soon) of rewiring my boat with all new battery cables, when I rewired my Mirage I used 1/0 for both, would you consider this over kill?

Thanks

Ayuh,.... When it comes to battery cables,... Bigger Is Better,....

I use weldin' cable, as it's a finer wire, with lower resistance,...

Make sure you use tinned marine wire no matter what size. If you just use copper it will eventually oxidize and drastically increase it's resistance. This will be particularly true in wet parts of the boat such as the engine bay. I think it is also a good idea to seal the terminals with good, waterproof (adhesive lined) heat shrink tubing.

I did the exact thing with my Mirage (Tinned), I bought a tinning pot just for that purpose and heat shrink tube for the ends, only reason I was/ am asking is I had someone tell me that you can go to large and it will be counter productive. So I wanted to check before I order my wire again.

Thanks
Bryan

Too large is just harder to run. The larger the wire the less voltage drop

One of the few times where bigger is better.

marine cabling also resists gas/oil/UV/corosion and proper marine connectors/lugs with proper crimping and insulators to resist loosening from vibrations.

whatever u do, dont listen to anyone telling you to go buy "welding cables." /facepalm.

I am going to order the 1/0 cable again that I got a few years back, as far as the lugs go, they come with solder cups and are soldered in, then I use 3mil thick shrink tubing and extend 2" back of the solder joint.

Too large of a cable becomes an issue just like too small in the areas of sound reproduction......especially on the ac side.

Batteries......nahhhhh. I run O/O in my boat....

im not sure why this thread exists. you're doing everything "the right way" :)
