Marine electronics repair on Long Island — we find the fault, then fix it.
Most marine electronics that stop working are not broken. They have a corroded ground, a voltage drop,
a bad connector or a network fault upstream. We do marine electronics repair
across Long Island at your slip — diagnosed properly before anything gets replaced.
Boat electronics repair for chartplotters, radar, VHF, autopilots, gauges, stereo and trolling motors.
NMEA certified, ABYC electrical standards, fully insured, 60-day labor warranty.
The Work
Marine electronics we repair and service.
From a single gauge reading wrong to a whole NMEA 2000 backbone dropping nodes. We carry common repair
parts and can source most manufacturer parts in a few days.
Displays & Chartplotters
Units that will not power up, reboot underway, lose GPS lock or show a black screen. Usually the supply circuit rather than the display.
Radar, AIS & VHF
Radomes that will not turn, missing returns, a VHF that receives but will not transmit, DSC that was never programmed. Often coax and connector corrosion.
NMEA 2000 Networks
Devices dropping off the backbone, a missing terminator, an overloaded power tap, a bad tee. One faulty node takes the whole network down.
Gauges & Senders
Tachometers, speedometers, fuel and tank senders reading wrong or not at all. Nearly always the sender, the ground or the wiring — not the gauge.
Autopilots
Not holding course, not engaging, wandering in a following sea. Compass calibration, heading sensor or feedback unit. We stay clear of hydraulic drive units.
Wiring & Power
Corroded terminals, undersized runs, wire nuts below the sole, a ground that floats. The root cause behind most "dead electronics" calls.
Sound Familiar?
The calls we get every week.
Marine electronics fail in a short list of patterns. Troubleshooting one is mostly a matter of having
seen it before — if you are looking at any of these, we have, and we can often narrow it down before we
arrive if you email a photo of the panel.
"It works sometimes"
The single most common fault and the hardest to catch. A bad connection reads perfectly
fine on a dead circuit and fails the moment real current goes through it — so we load test and measure
voltage drop across the run instead of checking continuity. It is a connection, not the box, almost
every time.
Green terminals and a floating ground
Long Island boats sit in salt air eight months a year. Dissimilar metals, a damp bilge
and a bonding system doing its job add up to corrosion at every termination. Most "electrical gremlins"
on a ten-year-old boat are twenty corroded terminals rather than one failed component. We re-terminate
to standard and protect it so the repair outlasts the season.
Gauges & Instruments
Gauge repair and instrument restoration.
A gauge reading wrong is one of the cheapest faults to fix and one of the most commonly misdiagnosed.
Before anyone buys an instrument we test the sender, the ground and the run between them — which is
where the fault usually is.
Gauge Repair
Faria, Faria Beede, Teleflex, VDO and Yamaha instruments. Tachometers, speedometers, voltmeters, oil and water temperature.
Tank & Fuel Senders
A fuel gauge that reads full forever, or empty at half a tank, is nearly always the sender or its ground rather than the instrument.
Panel Restoration
Faded faces, failed backlighting, cracked bezels and corroded studs behind the dash. Restored in place, or rebuilt as a new panel if the helm warrants it.
If the panel itself is past saving rather than the instruments in it, a
custom dash panel is often the better answer —
same helm, modern instruments, a finish that matches the boat.
Repair Near You
Marine electronics repair near me — wherever the boat is on Long Island.
There is no shop to bring the boat to, because the shop comes to the boat. We work at your slip,
mooring, boatyard or driveway across Nassau and Suffolk County — the South Shore bays, the North
Shore harbors and the East End. Travel up to 30 minutes each way is already inside the first hour;
past that it is $40 per half hour per man, door to door, so a Montauk call costs what it costs and
nothing more.

Brands
Garmin, Raymarine, Simrad and Furuno repair — brand by brand.
We repair and service all the major marine brands. Where a manufacturer requires their own authorised
service centre for a warranty claim we will tell you that plainly rather than take the job and hand you
a problem.
Garmin Repair
GPSMAP and echoMAP displays, GMS network switches, Reactor autopilots, Fantom and xHD radar, Force trolling motors and VHF 215/315 radios.
Raymarine Repair
Axiom and eS displays, Evolution autopilots, Quantum and magnetron radar, i-series instruments and Ray VHF sets.
Simrad & B&G Repair
NSS, NSO and GO displays, AP autopilots, Halo radar, Triton and Zeus instruments, and the NMEA 2000 backbones behind them.
Lowrance Service
HDS and Elite units, StructureScan and ActiveTarget transducers, and the Ethernet and N2K networking between them.
Furuno & Humminbird
NavNet and TZtouch displays, Furuno radar and sounders, Humminbird HELIX and SOLIX units and their transducers.
Icom, Standard Horizon & Fusion
Fixed-mount VHF with DSC and AIS, hailers and marine audio head units, amplifiers and speakers.
Also Repaired
Marine stereo and trolling motor repair.
Two things people are often told to replace when a repair would have done.
Marine stereo, amps and speakers
Marine audio fails in predictable ways — corroded speaker terminals, water into an
amplifier, a head unit wired to a circuit that browns out when the blower starts. We repair the wiring
and the terminations rather than selling you a new system, and if a unit is genuinely dead we say so.
Marine sound system installation if you are upgrading rather than repairing.
Trolling motor repair
Minn Kota and Garmin Force. Foot pedals, mounts, the bow plug, the high-current
connections and the wiring back to the bank. Trolling motor faults are usually those connections
rather than the motor itself, and connections are repairable.
Trolling motor installation if you are fitting a new one.

Honest Assessment
When to repair, and when to replace.
Not every failure is worth repairing, and we would rather tell you that than take the money.
Usually worth repairing
- Wiring faults, corroded terminals and bad grounds
- NMEA 2000 network problems — terminators, tees, power taps
- Transducer cable breaks and connector damage
- Gauge faults that trace to a sender or a ground
- Radar and VHF coax and connector corrosion
- Marine audio wiring and speaker terminations
These are mechanical problems. They are almost always cheaper to fix than to replace.
Usually worth replacing
- Cracked screens and failed backlights on older displays
- Units the manufacturer no longer supports with charts or firmware
- Anything where a factory repair costs more than a current model
- Water-damaged boards — a repair rarely holds
A new chartplotter with current cartography often costs less than a factory repair on a
ten-year-old unit, and you get a warranty with it.
Our Work
What a proper repair looks like.
Labeled, terminated to standard, and left so the next person can follow it — the difference between a
repair and a patch.
How It Runs
From your call to sign-off.
Four steps, and you know the cost basis before anyone comes out.
1 — Tell Us What It Is Doing
The boat, the marina, and the symptom. A photo of the panel or the fault tells us more than a paragraph and often narrows it before we arrive.
2 — We Come To The Boat
At your slip, mooring or yard, anywhere in Nassau or Suffolk. Travel up to 30 minutes each way is already inside the first hour.
3 — Diagnosed To Root Cause
Meter, diagram and load testing. You are told what is actually wrong and roughly what it takes to fix before we carry on — no parts swapped on a guess.
4 — Repaired And Tested
Fixed to ABYC standard, terminated properly, labeled, then tested with you on the boat. Sixty-day labor warranty on what we did.
One Person, Start To Finish
The person on the phone is the person on the boat. Nothing gets lost between a dispatcher, a salesman and a tech who has never seen the job.
Parts We Supply
We install what we supply, at cost plus markup, so the warranty and the responsibility sit in one place.
Costs Up Front
What marine electronics repair costs.
Time and materials, always. Repair work is diagnostic by nature — anyone quoting a firm price for a
fault they have not seen is guessing, and you pay for the guess either way.
$280 First Hour
One technician. Includes travel up to 30 minutes each way and setup. No separate setup line, and no four-hour minimum.
$140/hr After
Billed in 15-minute steps, so a 20-minute fix costs 20 minutes. A two-man crew is $440 first hour then $220/hr where the job needs it.
Parts & Travel
Parts at cost plus markup. Travel past 30 minutes each way is $40 per half hour per man, door to door. Multi-day work restarts the first-hour rate each day.
Bench and shop time is $125/hr, never the field rate. Diagnostic time is billable whether or not you
go ahead with the repair — you are paying for the fault to be found. Fair pricing, with the cost basis
given to you before the work starts.

What Customers Say
Real reviews from real boat owners.
Michael B.
★★★★★
Great service. Fixed all issues promptly. Would recommend to anyone needing boat servicing.
AJ S.
★★★★★
I had tried getting an appointment with several other companies, but could not get anyone to come down and take a look. When I contacted LIME I got Dave the owner on the phone and he was very knowledgeable. He was able to come out the same day I called to get an appointment and was able to diagnose the problem right away. I would absolutely use them again.
Adam R.
★★★★★
David came on to my Boat and offered me several options and always leaned towards trying to save me the most money. His work was impeccable and delivered everything he said in a timely manner. if he says he will meet you at your boat at 8:30 then he is there at 8:29. In the boating world it is tough to find reliable people. He is a breath of fresh air.

Is there a marine electronics repair service near me that comes to the boat?
Yes — that is how we work. We come to your slip, mooring, boatyard or driveway anywhere in Nassau or Suffolk County: the South Shore from Freeport to Patchogue, the North Shore from Port Washington to Port Jefferson, and the East End out to Montauk. Travel up to 30 minutes each way is inside the first hour; past that it is $40 per half hour per man, door to door.
Do you repair Garmin, Raymarine and Simrad electronics, or only install them?
Both. Repair is most of what we do in season — a display that will not power up, a radar that will not spin, a network dropping nodes, a VHF that receives but will not transmit. We diagnose to root cause first, and if the unit itself is dead we tell you whether a factory repair or a replacement makes more sense.
What if you diagnose it and I decide not to repair it?
You pay for the time it took to find the fault, and nothing else. Diagnostic time is real work — meter, wiring diagram, load testing — and it is billable whether or not you go ahead. If the repair is not worth the money we will say so and tell you why, with no pressure either way.
Can you repair at my slip, or does the boat have to go somewhere?
Almost all of it happens at your slip. We bring diagnostic gear, common parts and tools to every call. Component-level bench work — soldering, a factory firmware load, an internal board repair — may need the unit to come off the boat, and we will tell you before we take anything.
Do you repair gauges and instrument panels?
Yes. Faria, Teleflex, Faria Beede and VDO gauges, tank senders, tachometers and speedometers. A gauge reading wrong is more often the sender, the ground or the wiring than the gauge itself, so we test the circuit before anyone buys a new instrument. Full panel restoration is also something we do — see the dash panels page.
Which brands do you service?
Garmin, Simrad, Raymarine, Lowrance, Furuno, B&G, Humminbird, Standard Horizon, Icom, Fusion and Minn Kota, among others. For a warranty claim some manufacturers require their own authorised service centre, and we will tell you plainly if your unit falls into that category rather than taking the job.
Can you fix a marine stereo or speakers?
Yes — head units, amplifiers, speakers and the wiring between them. Marine audio fails in predictable ways: corroded speaker terminals, water in an amp, a head unit wired to a switched circuit that browns out. Usually a wiring repair rather than a replacement.
Do you repair trolling motors?
Yes. Minn Kota and Garmin Force — foot pedals, connectors, wiring, mounts and the plug at the bow. Trolling motor faults are usually the high-current connections rather than the motor, and those are repairable.
My electronics work sometimes and not others. Can that be found?
That is the most common call we get, and it is the reason we work with a clamp meter rather than a continuity tester. A connection that fails intermittently reads fine on a dead circuit and fails under real load — so we test under load and measure voltage drop across each run. It is almost always a connection, not the box.
How long will it take?
A wiring fault, a bad connection or a blown fuse is usually a single visit. Anything needing a part ordered typically runs three to seven business days. We tell you a realistic range up front and bill only the hours actually worked.
What warranty comes with a repair?
Sixty days on our labor. Any part we supply carries the manufacturer’s own warranty, which on most marine brands is two years or better.
Something on the boat stopped working?
Tell us the boat, the marina and what it is doing. A photo of the panel helps. We will tell you what it
is likely to be and what it takes to put right.
