Marine electronics repair — board level

We diagnose fishfinders, chartplotters, radar, VHF, autopilots, and trolling-motor boards down to the component that failed, then repair the board itself. Marine dealers are mostly set up around flat-rate exchange, because a microscope bench doesn't fit that model.

The Space Coast’s board-level marine repair

Most marine dealers and manufacturers have stepped back from real repair. Bring in a fishfinder or chartplotter with a dead board and the standard answer is a flat-rate exchange, often $850 to $1,600 for a mid-range unit, rather than a diagnosis of what actually failed. That’s scan-and-replace, and it’s the industry default now.

We do the opposite: open the unit, find the failed component or corroded trace, and repair the board itself. It’s the Space Coast’s only board-level marine electronics repair, and the work is real component- and connector-level rework on the board itself.

Saltwater is the enemy, and it’s constant

With roughly 33,000 registered boats running in local saltwater, corrosion-driven electrical failure is routine rather than rare. Salt air and spray get into connectors, headers, and board traces long before a hull shows its age, and the failure often shows up as a unit that won’t power on, won’t hold a GPS fix, or drops sonar return out of nowhere. That’s a corrosion problem at the board level, and it’s usually recoverable if the corrosion hasn’t fully bridged or eaten through a trace.

What we repair

Fishfinders and depth sounders, chartplotters and multifunction displays (MFDs), marine radar, VHF radios, autopilots, and trolling-motor control boards, across Garmin, Humminbird, Lowrance, Raymarine, Simrad, and Furuno. If it’s a circuit board and it’s worth saving, it’s worth a look.

How it works

Every unit gets a free diagnosis first, with no obligation and no diagnostic fee. From there it’s a firm quote, your go-ahead, then the repair. Nothing happens to your board until you approve the price.

Local drop-off, or mail it in

Drop off in Palm Bay or Melbourne, or ship it in; the process is identical either way, and it’s how we serve boat owners well outside Brevard County who don’t have a board-level option any closer to home.

How it works

Four steps. You approve before we start.

Drop off in Palm Bay or Melbourne, or mail it in from anywhere. Same process either way.

Diagnose

We open it up and find the real fault at the component level.

Free · no obligation

Firm quote

A fixed price and turnaround — no surprises, no diagnostic fee.

You approve

Nothing happens to your board until you say go.

Repair & return

Component-level repair, tested, and back to you.

FAQ

Frequently asked

Can a water- or corrosion-damaged marine unit be repaired?

In many cases, yes — saltwater corrosion damage is repairable if it’s caught before the corrosion fully bridges or eats through a circuit trace. Every unit gets a free diagnosis to determine whether the board is a realistic repair before any work or cost is involved.

Do you repair marine electronics from any brand?

We work on the major marine electronics brands, including Garmin, Humminbird, Lowrance, Raymarine, Simrad, and Furuno. If your brand isn’t listed, ask anyway, because board-level repair usually comes down to the specific fault on the board rather than the badge on the case.

The OEM only offers a flat-rate replacement — can you actually repair mine?

Often, yes. Many marine electronics manufacturers now respond to a failed unit with a flat-rate exchange rather than a genuine repair, and board-level repair is the alternative to that replacement cost for units that are still repairable.

Do you offer mail-in marine electronics repair?

Yes — the process is the same whether you drop the unit off in Palm Bay or Melbourne or ship it in from anywhere in the country: free diagnosis, a firm quote, your approval, then the repair.
