As boating season kicks into gear, it’s the perfect time to check your electrical systems. Worn or damaged marine wire can cause frustrating issues—or even put you at risk on the water. Here are five signs it may be time to upgrade to new marine wire before your next trip.
1. Cracked or Dry Insulation
If your boat wire feels brittle or shows signs of cracking, sun and salt may have taken their toll. Marine grade wire is built to withstand harsh conditions, but nothing lasts forever.
2. Green or Corroded Ends
Corrosion at terminals or connectors is a clear sign it’s time for marine cable replacement. Look for discoloration or a powdery green buildup—especially around your marine battery cable.
3. Inconsistent Power
Flickering electronics or spotty power to devices can often be traced back to bad connections or old marine wiring. Start by checking your marine grade wire connectors.
4. Stiff or “Crunchy” Wire
Over time, even high-quality 8 gauge marine wire or 6 gauge marine wire can become rigid. If it doesn’t bend easily, it’s likely time to replace it.
5. Unknown Age
If you’re unsure how old your 12 gauge wire is—or if the boat came with pre-installed wire—it’s safer to replace it with new, tinned marine wire for boats.
