Marine Electrical Services
Traced. Tested. Fixed. Not Guessed At.
Marine Electrical Done Right
Electrical problems on a boat can range from mildly annoying to genuinely dangerous. A dead battery bank leaves you stranded. A corroded connection kills your bilge pump. A bad ground causes stray current corrosion that eats through your hull hardware. In the Keys, you do not want to guess at electrical work.
3 Marine Mobile KW approaches marine electrical methodically. We use proper testing equipment — multimeter, clamp meter, load tester — to trace problems to their source. We fix the root cause, not just the symptom. All wiring work meets ABYC standards and is documented.
