Dave and Adam did a great job installing my new trolling motor, heading sensor, batteries, switch, and charger. They even modified my bow rail for the motor to deploy. They were easy to work with and the project turned out great. I recommend LIME very highly.

★★★★★
Great install by David and his team! Complete electronics update, with new panels, gauges & switches. David is very meticulous, detail oriented in his planning and installation. Great communication throughout the process, and finished the project on-time.

What we do for Long Island boats and fleets.
From single-helm refits to full commercial fleet electronics — chartplotter installs, dash panel builds, marine sound system installation, and wiring troubleshooting for private boats, charter operators, party boats, and municipal marine departments across Nassau and Suffolk County.
We diagnose first, install clean, and stand behind every job.
Marine systems fail in ways that punish shortcuts. Bad routing, poor mounting, sloppy wiring, and messy helm layouts all cost more later — on a private helm or a working charter.
- Installation, troubleshooting, and full helm upgrades — all under one roof.
- Experience across private, charter, and municipal work — from a single chartplotter to a full fleet refit.
- Custom dash panels and helm upgrades that look like they came from the factory.
- Public pricing so you know what to expect before you pick up the phone.
- We know Garmin, Simrad, Raymarine, and Furuno inside and out.

Frequently Asked Questions
Do you service Nassau County and Suffolk County?
Yes. Long Island Marine Electronics provides onsite marine electronics service across both Nassau County and Suffolk County. We come to your boat at your marina, mooring, or boatyard — no need to trailer it anywhere. We cover marinas from Lawrence and Oyster Bay to Fire Island, Babylon, Islip, and Montauk.
What brands of marine electronics do you install?
We install and service Garmin, Simrad, Raymarine, Furuno, FLIR, ICOM, Fusion, and more. Our NMEA certification covers the full range of modern marine electronics networks, including NMEA 2000 and NMEA 0183 systems. We carry and install new equipment and can integrate your existing gear into a unified network.
Are you NMEA certified?
Yes. Long Island Marine Electronics holds NMEA Certified Marine Electronics Installer status — the marine electronics industry's professional installer credential. NMEA certification requires demonstrated competency in electronics installation, network integration, and ABYC safety standards. It is the benchmark serious boat owners use to evaluate installers.
Do I need to bring my boat to a shop?
No. All work is performed onsite at your marina, mooring, or boatyard on Long Island. We come to you anywhere in Nassau County or Suffolk County. No haul-out, no trailer, no shop drop-off required. We bring tools, parts, and expertise directly to your vessel.
How much does marine electronics installation cost on Long Island?
Your first hour is $280 flat — travel (up to 30 minutes each way), setup, and the first hour of work included — then $140/hr in 15-minute steps. A second installer is $160 for his first hour, then $80/hr. Shop, admin, and R&D time is $125/hr. Parts and materials are quoted separately. Every job starts with a realistic scope estimate so you know what to expect before work begins.
How soon can you get to my boat?
Usually on your boat within two to three days. We answer calls and quote requests within one business day, and we come to you at your marina, mooring or boatyard anywhere in Nassau and Suffolk County, so there is no hauling and no shop drop-off. Call 516-448-6221 and tell us where the boat is and what it is doing.
Can you work on my boat over the winter while it is stored?
Usually, yes. We come to the boat where it sits, in the yard, under shrink wrap or in a barn, anywhere in Nassau and Suffolk County. Winter is a good time for bigger jobs like a helm rebuild, because the boat is out of the water anyway. If your yard has access rules, tell us early so the work goes on the schedule properly.
Do you need shore power at my slip?
For most installations, yes. Running tools, testing electronics and charging equipment all need 30A or 50A shore power. If your slip does not have power, we can often use a generator, so mention it when you schedule. We do the work at your marina, so there is no need to haul the boat or bring it anywhere. Questions? Call 516-448-6221.
Can I get a price before paying for a visit?
Yes. Email us photos and model numbers and we will price it by email at no charge, no trip needed. When a job needs someone to look at the boat first, it is a paid service call: $280 flat for the first hour, including travel up to 30 minutes each way and setup, then $140/hr in 15-minute steps. There is no minimum.
