Marine electronics installation and upgrades including chartplotters, fish finders, VHF radios, audio systems, navigation lights, and electrical systems.
The short answer: anything that makes you safer, helps you find fish, or keeps you from getting lost on the water. The longer answer depends on how you use your boat.
At Atlantic Boat Repair we install and wire marine electronics for South Shore boaters from Plymouth to Falmouth. Chartplotters, fish finders, VHF radios, audio systems, navigation lights, and battery management are the most common upgrades we see. Ron has been doing this for 50 years, and the single biggest mistake he sees is customers buying good equipment and then having it installed poorly. A chartplotter that loses connection at 20 knots, a VHF antenna with bad coax, or a stereo that pops a fuse every time the bilge pump runs are all installation problems, not equipment problems.
We are NMEA-certified, which means we understand how these systems talk to each other. Most modern marine electronics run on an NMEA 2000 network, a backbone that lets your chartplotter, fish finder, engine data, autopilot, and depth sounder share information. Done right, one display shows everything. Done wrong, you have five standalone devices with no communication and wiring that looks like a bowl of spaghetti.
We work on all major brands: Garmin, Lowrance, Humminbird, Simrad, Standard Horizon, Fusion, Kenwood, and more. We will tell you which unit fits your console space and budget before you buy anything. Bring the boat in and we will give you an honest assessment of what your current setup can support and what is worth upgrading.

Can’t say enough good things about Atlantic Boat Repair. Ron, Ryan, and the whole team were awesome to work with. They got my 2003 Montauk in quickly, installed my new Garmin, repaired my lower unit, kept me updated throughout the entire process, and had me back on the water just a couple of days later, right before the holiday weekend. They even sent one of their guys to pick up a part the same day so there wouldn’t be any delays getting us back out. The communication, turnaround time, and quality of the work were all exceptional. Finding a shop you can truly trust is hard, and I genuinely won’t take my boat anywhere else. They’ve earned a customer for life! Thanks again, guys!

I recently had to upgrade my older outboards to something a little newer and with more horsepower. Ron and Ryan were extremely helpful when I was looking for engines, and when I did find a pair of 250's, they took delivery of them, removed my old engines and had the new ones installed in no time. We also worked through some electronics upgrades as well. They had some great suggestions and I'm extremely happy with the end result. The communication through the whole process was outstanding, they would always provide updates and expected completion date. This all occurred during one of their busiest times of the year. Can't say enough good things about the team at Atlantic!

I’ve had a boat for many years and had gone to various shops for winterizing and repairs. Some took forever to complete the work and others ignored (more than once) my request to look at an electronics issue I was having. Then I found Atlantic! Ryan has been absolutely great for the past several years I’ve been going there. I don’t think there is anything they don’t do! I’ve had new electronics, winterizing, engine maintenance, even trailer repair. They do detailing too. Always a fair price and they are extremely responsive. I’ve referred 3 other friends there who have all been satisfied customers.

Common questions about our marine electronics & upgrades services.
Both. We can source equipment for you or install gear you already purchased. If you buy through us, we make sure what you get is compatible with your existing setup before it ships.
Garmin, Lowrance, Humminbird, Simrad, Standard Horizon, Fusion, Kenwood, and most other major marine electronics brands. If you have something less common, call and we will let you know.
NMEA 2000 is the standard network protocol that lets modern marine electronics share data. If you have a newer chartplotter, fish finder, or engine with digital gauges, they likely already support it. A proper backbone install means all those devices talk to each other instead of working independently.
A single device like a VHF radio is usually a half-day job. A full multifunction display with transducer, NMEA 2000 integration, and new audio is typically one to two days depending on the boat layout.
Customers bring their boats to our Plymouth shop from these towns.
