Hear from Our Customers
You’re not looking for the cheapest marine electronics job. You want systems that work when you need them, installed by people who understand what you’re dealing with out there.
When your navigation cuts out 20 miles offshore or your fishfinder stops working during the bite, that’s not just inconvenient—it’s expensive. Good marine electronics installation means using the right components, proper waterproof connections, and understanding how saltwater and vibration affect every wire and circuit.
Your boat deserves better than car stereo speakers that’ll fail in six months or GPS units that can’t handle spray. We install marine-grade systems built for the environment, connected properly the first time.
Legacy Motors and Marine brings the same attention to detail we use for high-end vehicle storage to marine electronics installation. We understand that your boat represents a significant investment, and the electronics need to match that level of quality.
Located in Port Jefferson Station, we’ve been serving South Setauket and Long Island boat owners who expect professional results. We’re not the guys who’ll string you along for months or leave you with half-finished installations.
Long Island’s marine community has high standards because the conditions demand it. From the Sound to the Atlantic, your electronics face salt spray, humidity, temperature swings, and constant vibration. We install systems that handle it all.
First, we assess your current setup and discuss what you actually need—not what we want to sell you. Every boat is different, and every owner uses their vessel differently. A fishing setup needs different electronics than a cruising yacht.
Next, we plan the installation with proper wire routing, waterproof connections, and integration with existing systems. We use marine-grade components designed for saltwater environments, not automotive parts that’ll corrode in months.
During installation, we protect your interior and ensure clean, professional wire runs. Every connection gets proper sealing, every circuit gets appropriate fusing, and everything gets tested before we consider the job complete. You’ll know how to operate your new systems before we leave.

Our marine electronics installations include custom boat stereos and audio systems designed for the marine environment, with speakers that won’t fail when they get wet and head units that resist salt corrosion. We handle complete navigation and GPS systems installation, from basic chart plotters to integrated radar and autopilot systems.
Custom wiring and electrical work ensures everything connects properly and safely. We install dedicated circuits for high-draw equipment, proper grounding systems, and waterproof connections throughout. Fishfinder and sonar installation includes transducer mounting, cable routing, and integration with existing electronics.
South Setauket boat owners face unique challenges with Long Island Sound conditions—from fog that requires good radar to fishing spots that demand reliable sonar. We install systems that perform in these specific conditions, not generic setups that work everywhere but excel nowhere.
Installation time depends on the complexity of your system and your boat’s existing setup. A basic stereo upgrade might take a day, while a complete navigation system with radar, GPS, and fishfinder integration could take several days.
We don’t rush jobs to fit more boats into our schedule. Proper marine electronics installation requires time for correct wire routing, waterproof connections, and thorough testing. We’ll give you a realistic timeline upfront and stick to it.
Most importantly, we complete one installation properly before moving to the next. You won’t be waiting weeks between visits while we juggle multiple partial jobs.
Marine electronics face conditions that destroy car audio equipment quickly. Salt air corrodes connections, humidity penetrates circuits, and constant vibration loosens components. Car stereo speakers use paper cones that disintegrate when wet, while marine speakers use waterproof materials like polypropylene.
Marine head units have conformal coating on circuit boards—a protective layer that seals components from moisture. They also use stainless steel chassis and rubber gaskets around access doors. These features add cost but prevent the failures you’d see with automotive equipment.
The wiring is different too. Marine installations require tinned copper wire that resists corrosion, proper grounding systems, and waterproof connections throughout. Using the wrong materials means replacing everything in a year or two.
Yes, we specialize in integrating new marine electronics with existing systems. Modern chart plotters can network with autopilots, radar, sonar, and engine monitoring systems to share data and provide unified control.
We assess your current setup first to determine what can be integrated and what needs upgrading. Sometimes older equipment can’t communicate with newer systems, but we’ll explain your options clearly before starting work.
Integration planning is crucial for complex systems. We map out data networks, power requirements, and display layouts to ensure everything works together properly. The goal is a cohesive system that’s easier to use, not a collection of individual components.
We warranty our installation work because we use proper techniques and marine-grade materials. Our installations include waterproof connections, appropriate fusing, and correct wire sizing—the fundamentals that prevent most electronics failures.
Equipment warranties come from manufacturers, but installation problems are on us. If a connection fails because of our workmanship, we fix it at no charge. If equipment fails due to manufacturing defects, we help coordinate warranty service.
We also provide post-installation support. Marine electronics can be complex, and we want you comfortable using your new systems. We’re available for questions and can walk you through operations until you’re confident.
We install and service all major marine electronics brands including Garmin, Raymarine, Simrad, Furuno, and Lowrance. Each brand has strengths in different applications—some excel at fishing electronics, others at navigation systems.
We recommend equipment based on your specific needs and boat type, not what we have the most markup on. A serious fisherman needs different sonar capabilities than a weekend cruiser, and we match systems accordingly.
Our technicians stay current with training from major manufacturers. Marine electronics technology evolves quickly, and proper installation requires understanding each system’s specific requirements and capabilities.
We handle marine electronics troubleshooting and repairs for systems we’ve installed and existing equipment. Common problems include corroded connections, failed displays, and networking issues between integrated components.
Troubleshooting marine electronics requires understanding both the equipment and the marine environment. Water intrusion, corrosion, and vibration cause specific failure patterns that we recognize quickly. We carry diagnostic equipment to test systems properly.
For complex repairs, we coordinate with manufacturer service centers when needed. Some issues require factory service, but many problems stem from installation issues or environmental damage that we can address locally. We’ll always explain what’s wrong and give you options for repair or replacement.
