See full version: What is the issue with wingnuts on the battery
The average, true "Marine Grade" battery, comes with both automotive style lead posts and threaded stainless steel or nickle plated posts. In some cases the automotive style posts are not present. You should use the threaded posts to reduce the potential for problems with corossion. I rarely see the more expensive brand names with wing nuts any more. I use a stainless nut with a lock washer just like you'll find on the better battery switches out there. more
Re: What is the issue with wingnuts on the battery?
On my previous boat, I installed real battery terminals when I re-wired the boat. On my new boat, however (1988 Stingray SVB 176, Mercruiser 3.0L), it has come to me with wingnuts securing the battery cables to the battery. I have seen a few warnings from time to time that you shouldn't use wignuts and screw terminals for connections. Can anyone tell me why? Mostly curious, but if there is a reason to, I'll change over to battery terminals in the off season.

When purchasing UF cable, you should take special care to differentiate it from ordinary NM (non-metallic, or Romex) cable. Usually, UF cable has information printed on the sheathing that identifies it as UF.

You may plan to install electrical wire outdoors for operation of pumps, lighting, and other apparatuses. Whatever the purpose, you can run your wiring overhead or in a below-ground trench. If you choose a trench, you will need to know what types of wiring and conduits you can use and how deep to bury them. Below, you will find five tips about electric wire burial.
Before getting over-involved, however, you should check the local and municipal laws and regulations on cable burial, and with the local utilities so they can mark where their underground utilities lie on your property. Before starting any of the work, you should also apply for a construction and electrical permit, as it could be required in your municipality.
UF cable (underground feeder cable) is specially designed and manufactured with properties that make it ideal for burial. This cable should be buried at a depth of 24 inches. The cable is less likely to be cut or disturbed by typical digging if it is this far below ground. However, certain municipalities and states/provinces require that local utilities be contacted so that they can mark where their undergrounds utilities lie on your property.
If you ever find wires joined with electrical tape, or the wires are twisted together and then wrapped with electrical tape, get rid of the tape and join the wires with wire nuts. Never use tape in place of wire nuts—it's simply not secure enough, and it's vulnerable to damage. Some people like to use wire nuts and wrap them with tape. This fine to do, but you probably won't find any wire nut manufacturers advising you to do it.
Standard wire nuts are roughly conical in shape and usually have ridges on their sides so your fingers can get a good grip. Some types have little side wings instead of ridges. Inside the plastic cone is a little square-cut spring that provides tension on the wires to hold them securely. As you tighten the wire connector by twisting it, the spring draws tighter around the wires. Variations on classic twist-type wire nuts include push-in wire connectors (you push the straight wire ends into holes), waterproof wire connectors (usually gel-filled to keep out moisture), and butt-splice connectors (for joining wires end to end). more
Always follow the manufacturer's instructions, as techniques vary by product. But here's the standard procedure: here
While doing almost any kind of electrical wiring in your home, you'll likely run into wire connectors used to make a variety of different circuit wire connections for light fixtures, outlet receptacles, switches, and other devices. The most common type of wire connectors are little round little plastic caps, often called wire nuts, that twist over the bare ends of wires to make tight connections. Wire nut connections are reversible—they can be unscrewed in the future in the event that you need to replace any device.
