Marine Electrical Repairs and Upgrades at Defender

Are you familiar with the electrical system on your boat? If you aren't, you might want to familiarize yourself with it. There are times when that knowledge could come in handy. For instance, the Coast Guard doesn't care whether or not you know how to change a blown fuse. They will just give you a citation because your navigation lights aren't working!

Other simple repairs you should know how to do are: replacing cables, replacing worn battery terminals, fixing electrical terminals, and splicing wires. You should also know the type and size of electrical wiring on your boat.

What makes marine wire special?

The wiring on a boat needs to be reliable and corrosion-resistant. Marine wire is designed to withstand the harshest marine environment. It should safely resist the corrosive effects of saltwater for many years.

In order to ensure the safety of your boat and everyone aboard, it is vital that the correct gauge of marine grade wire is used, along with high-quality marine electrical connectors and components. All electrical work should be done by professionals or very experienced DIYers. According to BoatUS, 35% of all boat fires are caused by the DC electrical system. Together with the AC system, electrical fires account for over half of all boat fires.

The marine wire you choose needs to be large enough to carry the intended load. It should also be the right type for the installation. For instance, only wire that is oil resistant and heat resistant to 75° C (167° F) should be installed in the engine room. Consult a professional for wire recommendations and then check out our marine wire selection.

You should keep extra wire on hand and know how to splice it if needed. You will also want to have some spare electrical parts and the proper tools on hand so that you're prepared for any unexpected problems.
