Marine Electronics Upgrades on Long Island
Old chartplotter. Dim fish finder. VHF with no DSC. If your electronics are more than 10 years old, you are navigating with outdated information — and missing what modern gear can do. LIME upgrades marine electronics across Nassau and Suffolk County, from a single device swap to a complete helm refit.
NMEA certified, fully insured, Garmin, Simrad, and Raymarine authorized. We assess your setup, design the upgrade around what you are keeping, and install everything clean — NMEA 2000 backbone included when needed.
Signs It Is Time
How to know when your marine electronics need an upgrade.
Most Long Island boaters wait too long. The signs: a chartplotter that takes more than 90 seconds to boot, a display you cannot read in afternoon sunlight, chart cards no longer available for your model, or a fish finder with no CHIRP. These are not minor inconveniences — they affect safety, situational awareness, and your ability to find fish. Modern gear — with built-in AIS, radar overlay, and CHIRP sonar — is dramatically better than what was available 10 years ago.

Full Scope of Work
Every piece of electronics LIME upgrades on Long Island boats.
A marine electronics upgrade can mean one device or the entire helm. LIME designs the upgrade so everything communicates — chartplotter, fish finder, radar, VHF, and NMEA 2000 backbone working together from day one.
Chartplotter Upgrade
The most common and impactful upgrade. Modern 10 to 12-inch touchscreen MFDs include built-in AIS, radar overlay, CHIRP sonar, and wireless phone integration. LIME sizes the display to your helm and handles the cutout, mounting, and wiring.
Fish Finder & Sonar
Upgrade from basic depth to CHIRP sonar, side imaging, down imaging, and LiveScope. LIME verifies transducer compatibility and installs the display and transducer as a package.
VHF Radio Upgrade
Modern VHF radios include DSC with Class D controller, GPS integration, and AIS receive. If your VHF is more than 8 years old, it likely lacks DSC — which automatically sends your position in a distress call.
Radar Upgrade
Solid-state radar (Garmin GMR Fantom, Simrad Halo) cuts warm-up time to zero and improves close-range target detection. LIME handles mast or hardtop mounting and integration with the new chartplotter.
Autopilot System
Garmin Reactor and Simrad AP70 integrate with chartplotters for GPS-guided route following. LIME installs the drive unit, course computer, and control head — and calibrates the system for your boat.
NMEA 2000 Backbone
The backbone that lets all your electronics share GPS, depth, speed, and AIS data. LIME installs and terminates NMEA 2000 networks correctly — no daisy chains that cause intermittent failures.
How Much Upgrade Do You Need?
Single device, partial refit, or full helm rebuild — LIME does all three.
The right upgrade scope depends on what you are starting with, what you want to do on the water, and your budget. LIME assesses your current setup and recommends what actually makes sense.
Single Device Swap
Replace one unit — chartplotter, fish finder, or VHF — while keeping the rest. Takes 2 to 4 hours. Best when the rest of the helm is less than 5 years old.
Partial Refit
New displays plus NMEA 2000 backbone — the most common upgrade scope for boats with 8 to 12 year old electronics. Keep functional radar and VHF; replace chartplotter and fish finder. Typically 1 full day.
Full Electronics Refit
Complete helm rebuild — chartplotter, fish finder, VHF, radar, autopilot, and NMEA 2000 backbone. Best for boats 15 years or older. Fair pricing up front; 1 to 2 days to complete.

Brands We Install
Garmin, Simrad, and Raymarine — LIME is a certified installer for all three.
Authorized by the three leading marine electronics brands. If you have a preference, we work with it. If undecided, we recommend based on your boat and how you fish.
Garmin GPSMAP Series
Garmin GPSMAP 9x3 and 12x3 are the most popular chartplotters on Long Island boats — vivid displays, built-in AIS, and seamless Fantom radar integration. LIME is a Garmin authorized installer.
Simrad NSX / NSS Series
Preferred by offshore anglers for robust NMEA 2000 integration and Simrad Halo solid-state radar compatibility. Strong performer on larger boat applications.
Raymarine Axiom Series
Axiom Pro and Axiom+ displays feature Lighthouse charts and RealVision 3D sonar. Preferred on sailboats and coastal cruisers. LIME installs and calibrates Raymarine autopilots as well.
Our Approach
What LIME does on a marine electronics upgrade.
Every upgrade starts with a helm assessment — what you have, what you want to keep, and what the wiring behind the dash actually looks like. LIME gives you fair pricing up front covering equipment, labor, and hardware. No surprise charges. We test every device at dock and confirm all network communication before we leave.
- Helm assessment — equipment, wiring, and cutout sizes
- Fair pricing up front before any work starts
- NMEA 2000 backbone installed and terminated correctly
- All displays tested at dock — cable runs hidden and secured

What Long Island boaters say about LIME upgrades.
Mike T. — Islip
"Replaced a 2009 Lowrance HDS with a Garmin GPSMAP 923. Dave assessed the wiring first and caught a bunch of bad splices before they became a problem. Clean install, all networked through NMEA 2000. Night and day difference from the old unit."
Rich C. — Oyster Bay
"Full refit on my Regulator 31 — new Garmin chartplotter, fish finder, VHF with DSC, and Halo 20 radar. LIME sourced everything, handled the backbone install, and had it all done in two days. Helm looks completely different."
Pete M. — Babylon
"Was skeptical about upgrading the autopilot but LIME convinced me to add a Garmin Reactor. Now the boat holds a heading perfectly while I work the rods. They calibrated everything on a sea trial. Worth every penny."
Common Questions
Frequently asked questions about marine electronics upgrades on Long Island.
How do I know if it's time to upgrade my marine electronics?If your chartplotter takes more than 90 seconds to boot, your display is dim in afternoon sun, or your fish finder has no CHIRP — it is time. LIME can assess your current setup and recommend a path forward.

Can I upgrade just one piece of equipment or do I need to replace everything?
You can upgrade individual pieces. LIME designs the upgrade to work with what you are keeping, confirms compatibility with your existing wiring, and documents what will need to change.
What is the most impactful single upgrade for an older boat?
For most Long Island boaters, the chartplotter is the biggest single upgrade. A modern 10 to 12-inch touchscreen with built-in AIS, radar overlay, and CHIRP sonar integration transforms situational awareness at the helm.
How long does a marine electronics upgrade take?
A single-device swap takes two to four hours. A full helm refit with chartplotter, fish finder, VHF, and NMEA 2000 backbone takes one to two full days. LIME gives you fair pricing up front before starting.
Do you buy electronics or does the customer supply them?
LIME can supply equipment or install customer-supplied gear. Supplying through LIME ensures compatibility — we know which units work well together and which combinations to avoid.
Can you remove and reinstall old electronics if I sell the boat?
Yes. LIME removes electronics cleanly — capping wires and filling cutouts — and can reinstall the same gear on a new boat. Standard rate applies — $280 first hour with travel included, then $140/hr.
