Marine Electrical & Electronics in Delray Beach FL — Diagnosed and Fixed at Your Dock

The calls we run most in Delray Beach are batteries that won't hold charge, blown fuses that keep blowing, electronics that flicker or reboot, navigation lights that won't light, bilge pumps that cycle on their own, and trim/tilt or start systems that work intermittently. Any of those mean current is going somewhere it shouldn't — or not getting where it should. Warning signs include green corrosion on terminals, a hot smell near a panel, voltage that drops the second you key the engine, and a multimeter reading that swings under load.

DIY repairs fail on boats because marine wiring isn't house wiring. Tinned conductors, adhesive-lined heat shrink, marine-grade terminals and proper ground paths are non-negotiable — and Atlantic and ICW salt air will eat any shortcut within a season. The real skill is tracing the fault to the actual root cause instead of replacing parts and hoping.

Our electrical work splits cleanly into two halves. Marine Electrical Repair covers everything that powers the boat: batteries and battery switches, charging systems and alternators, busbars and grounds, fuse blocks and breakers, bilge and livewell pumps, navigation and courtesy lights, trim/tilt circuits, and the tangled harness behind the helm that nobody wants to touch. We chase parasitic draws, fix corroded grounds, and rewire what's past saving.

On the electronics side, Marine Electronics Installation handles new chartplotters, GPS, radar, VHF radios, fish finders and transducers, stereo systems, autopilots, and the NMEA 2000 backbones that tie them together. Whether you're upgrading a single MFD or wiring a full helm refit, we'll plan the layout, run the cables clean, and make sure every device talks to every other device the way it should.

Electrical and engine issues often overlap. A weak ground will throw an engine code, a bad start circuit can look like a fuel issue, and a dying battery can mimic ignition failure. If we find an underlying mechanical problem during diagnosis, we'll loop in Outboard Engine Repair so the boat leaves fixed, not just patched.

Boats kept in Delray Beach, Boynton Beach, Boca Raton, Highland Beach, Lake Worth Beach, Deerfield Beach, Hillsboro Beach, Lighthouse Point, Pompano Beach and Palm Beach live in some of the harshest electrical environments in the country. Constant humidity, salt spray off the Atlantic and ICW, and shore-power that varies from marina to marina all wear on terminals, grounds, and sealed connectors. Boats that sit in covered slips fare a little better, but only a little.

That's why local experience matters. We know the corrosion patterns to look for first, which connector styles survive here and which don't, and how to plan a wiring run that holds up through hurricane season. When an electrical fault is masking an engine issue, our Engine & Mechanical Services covers the follow-up — or contact us and we'll sort out which it is.

We come to you — every diagnosis and repair happens at your dock, slip, or driveway with no haul-out. We're MMI certified and insured, with years of saltwater electrical experience across South Florida and Palm Beach County. You'll get a real walk-through of the fault, an upfront price before any wire gets cut, and same-day service whenever we can fit it. For dead batteries, no-start situations, and other show-stoppers, we run 24/7 emergency calls.
