Chartplotter Installation for Long Island Boat Owners.
We install and integrate GPS chartplotters from Garmin, Simrad, and Raymarine on boats across Nassau County and Suffolk County.
From a single display replacement to a full helm rebuild with networked navigation, sonar, radar, and autopilot — we handle every part of the install, including the NMEA 2000 backbone that makes it all talk to each other.

What we install and integrate
Every chartplotter install includes the display, mount, wiring, and NMEA 2000 network connection needed to make it functional. We don't just hang a screen — we make sure it talks to your depth sounder, radar, VHF radio, autopilot, and any other instruments on the network.
We work with fixed-mount displays from 7" to 24", flush-mount and bracket installations, glass cockpit multi-display setups, and custom helm panels where the layout itself needs to change.
- Garmin GPSMAP, ECHOMAP, and Quatix series
- Simrad NSS evo3S, NSO evo3, and GO series
- Raymarine Axiom, Axiom Pro, and Axiom XL
- Furuno GP and NavNet series
- Multi-display helm layouts with shared network
- Sonar/fishfinder integration (CHIRP, ClearVü, SideVü)
- Autopilot and instrument integration
NMEA 2000 — the network that connects everything
Most modern GPS chartplotter systems and marine electronics run on an NMEA 2000 network — a single backbone cable that every device plugs into. GPS, sonar, radar, VHF, autopilot, engine data, and instruments all share data over this one network.
If your boat doesn't have an NMEA 2000 backbone, we install one. If it does but it's poorly wired or missing terminators, we fix it. Every chartplotter install we do includes a check of the full network — we verify every device is talking, every node address is clean, and there are no conflicts.
This is the part most installers skip. It's why boats end up with a chartplotter that shows GPS but no depth, or a radar that doesn't appear in the chart overlay. We do it right the first time.

Frequently asked questions
How long does a chartplotter installation take?
A straightforward display replacement on an existing NMEA 2000 network typically takes 3–5 hours. A new display with network wiring, sonar integration, and panel work can take a full day or more. We give you an accurate estimate before we start — all work is billed portal-to-portal with a 4-hour minimum.
Do you install chartplotters on any type of boat?
Yes — center consoles, walkarounds, express cruisers, sport fishing boats, and larger offshore vessels. We service boats at marinas across Nassau County and Suffolk County. For boats that can't come to us, we offer mobile installation service.
Can you replace just the chartplotter and keep my existing sonar transducer?
In most cases yes. If your existing transducer is compatible with the new display (same brand or NMEA 2000 compatible), we can connect it. If it's an older analog transducer, we may need to add a module — we'll walk you through options before you buy anything.
Which brand should I choose — Garmin, Simrad, or Raymarine?
All three are excellent. Garmin is the most intuitive and has the best sonar integration. Simrad is preferred on larger offshore boats and has a strong autopilot ecosystem. Raymarine has excellent radar integration and a loyal following. We install all three and can walk you through the differences for your specific boat and use case.
Do you offer mobile chartplotter installation?
Yes. We come to your boat at marinas across Long Island. See our mobile marine electronics service for details on service area and scheduling.
Chartplotter installation on Long Island — Garmin, Simrad, Raymarine.
A chartplotter installation is more than mounting a display. The right installation involves matching the unit to your boat and how you fish or cruise, correct transducer placement and cable routing for maximum sonar performance, NMEA 2000 network integration so your chartplotter receives engine data, depth, wind, and heading from other instruments, and final software configuration so every feature works correctly out of the box.
LIME handles every aspect of chartplotter installation — from selecting the right unit for your boat and budget to wiring, networking, transducer installation, and post-install training. You get a fully functional system, not just a mounted box.
Garmin chartplotter installations
Garmin GPSMAP 9000 and 8400 series for serious offshore fishing. Garmin Echomap series for budget-conscious installs. Garmin Force trolling motor integration with the chartplotter for spot-lock and route following. Panoptix LiveScope sonar for live forward and down scanning. We configure Garmin networks correctly — shared sonar, Panoptix modules, radar overlay, and autopilot integration.
Simrad chartplotter installations
Simrad NSS evo3S and NSX series for large multi-display offshore helms. Simrad GO series for single-station installs. Active Imaging 3-in-1 and Active Target live sonar. Halo radar integration. AP44 autopilot with NSS network integration. Simrad's multi-display networking is the best available for offshore sport fishing helms with large touchscreens.
Raymarine chartplotter installations
Raymarine Axiom and Axiom Pro series for all-around performance. Axiom XL for large cockpit displays. Dragonfly sonar integration. Quantum radar with DownVision and SideVision. Evolution autopilot with FLIR camera integration. Raymarine is a strong choice for boats already in the Axiom ecosystem or owners who prioritize radar integration.

More five-star reviews from Long Island boat owners.
★★★★★
LIME installed a full Simrad NSS setup with Halo radar and Active Target sonar. Perfect install, everything configured before they left the boat. These are real pros — not guys who install and leave you to figure it out.
— Tom B., Mako 284 CC
★★★★★
Had an NMEA 2000 issue no one else could solve. LIME found a bad terminator that was causing intermittent GPS drops. Fixed in two hours. Would have cost me a week chasing the wrong problem.
— Gary M., Albemarle 280
★★★★★
Full helm rebuild — new StarBoard panel, dual Garmin 9" displays, radar, AIS, and autopilot. Cleanest installation I've ever seen on a boat. LIME is in a different league.

How to choose marine electronics for your Long Island boat.
Choosing marine electronics is more complex than reading specs sheets. The right system depends on your boat, how you use it, where you fish or cruise, and what other electronics you already have on board. Here is what actually matters.
Start with the Chartplotter
The chartplotter is the hub of every modern electronics system. Choose your chartplotter brand first — then build the radar, sonar, autopilot, and instruments around it using the same NMEA 2000 network.
Size Matters for Offshore Use
For offshore fishing on Long Island, go larger on the display — at least 9 inches, preferably 12 or 16. Small screens in a wet cockpit with sunlight and motion are nearly unreadable.
NMEA 2000 First
Design your NMEA 2000 backbone before you buy a single device. The network is the foundation — everything else plugs into it. A properly sized and terminated backbone prevents most of the problems we diagnose.
Transducer Placement is Critical
The best sonar unit in the world performs poorly with a transducer in the wrong location or with a bad cable run. This is where professional installation pays for itself — we place it right the first time.
Plan for Radar
Even if you are not buying radar now, plan the cable route and mounting location during installation. Retrofitting radar to a finished helm is expensive and disruptive. Planning ahead costs nothing.
Get a Written Scope
Before any work starts, get a written scope that specifies every component, cable run, mounting location, and configuration step. Vague estimates lead to scope creep and bill surprises. LIME always provides written estimates.
We stand behind every installation we do.
LIME's workmanship is guaranteed. If something we installed fails due to our labor — a loose connection, a wiring error, a missed configuration step — we come back and fix it at no charge. We are not in the business of charging for our own mistakes.
Workmanship Warranty
Our installation labor is warranted against workmanship failures. Loose connections, incorrect wiring, misconfigured software — these are our responsibility and we fix them.
Equipment Warranty
Equipment warranties are handled through the manufacturer. For units still under warranty, we help you document the failure and work with the manufacturer on your behalf.
ABYC Standards
Every installation follows ABYC E-11 DC electrical standards — the industry benchmark for safe, durable marine wiring. This is our insurance against installation-caused failures.
