Hear from Our Customers
Your boat isn’t just transportation—it’s your gateway to Long Island’s best waters. When you’re navigating the Great South Bay or heading out to Montauk Point, you need marine electronics that perform flawlessly every time.
Professional installation means your GPS guides you safely home in fog. Your fishfinder shows you exactly where the stripers are holding. Your marine stereo delivers crystal-clear sound without cutting out when you hit rough water.
The difference between amateur and professional installation shows up when it matters most. We install marine electronics the right way—with marine-grade components, proper waterproofing, and integration that actually works together.
Legacy Motors and Marine has been serving boat owners throughout Holbrook and the greater Long Island area with professional marine electronics installation. We understand the unique challenges of boating in local waters—from the shallow bays to the open Atlantic.
Our team works exclusively with marine-grade components designed to withstand saltwater, humidity, and the constant vibration that destroys standard electronics. We’ve installed everything from basic stereo systems to complex navigation packages on vessels ranging from weekend fishing boats to luxury yachts.
Every installation is backed by our commitment to quality workmanship and long-term reliability. When you’re twenty miles offshore, you need electronics you can trust.
We start with a detailed consultation about your boating habits and electronic needs. Are you primarily fishing local waters or making long offshore runs? Do you need basic navigation or a full electronics suite? Understanding how you use your boat determines the right equipment and installation approach.
Next, we design a custom installation plan that integrates seamlessly with your vessel’s existing systems. This includes proper wire routing, power management, and waterproof connections that prevent the corrosion and failures common with amateur installations.
The installation itself uses marine-grade components throughout—from tinned copper wiring to waterproof connectors. We test every system thoroughly before you take delivery, ensuring everything works together as designed. You get a complete walkthrough of your new electronics so you’re comfortable operating everything from day one.

Our marine electronics installation covers everything you need for safer, more enjoyable time on the water. Custom marine audio systems deliver concert-quality sound that cuts through wind and engine noise. Professional GPS and chartplotter installation gives you precise navigation with detailed charts of Long Island waters.
Fishfinder and sonar installation is optimized for local fishing conditions—whether you’re targeting fluke in the bay or tuna offshore. We understand the specific requirements for different fishing styles and can recommend the right transducer placement and settings for your preferred fishing spots.
All wiring and electrical work meets marine standards for corrosion resistance and safety. Holbrook boat owners deal with challenging saltwater conditions, and our installations are designed to perform reliably season after season. Every connection is properly sealed and protected against the marine environment.
Most marine electronics installations take between one to three days, depending on the complexity of your system. A basic stereo and GPS setup can often be completed in a single day, while comprehensive electronics packages with multiple displays, radar, and fishfinders typically require two to three days.
The timeline also depends on your specific vessel and any custom fabrication needed for clean, professional mounting. We always provide a realistic timeline upfront and keep you informed if we encounter any unexpected challenges during installation.
We’d rather take the time to do the job right than rush and create problems down the road. Quality installation work simply can’t be rushed, especially when dealing with the harsh marine environment.
Marine electronics are specifically designed to withstand saltwater, constant moisture, and extreme temperature variations that would destroy automotive electronics within months. Marine-grade components use corrosion-resistant materials and waterproof sealing that automotive electronics simply don’t have.
The wiring is completely different too. Marine installations require tinned copper wire and waterproof connections to prevent the corrosion that kills automotive-grade wiring in saltwater environments. Standard automotive wire will literally dissolve in marine applications.
Marine electronics also handle power fluctuations better. Boat electrical systems are notoriously unstable compared to automotive systems, and marine electronics are designed to operate reliably despite these power variations. Using automotive electronics in marine applications is a recipe for expensive failures and safety issues.
We install marine electronics on everything from small fishing boats to large yachts, but each vessel presents unique challenges that require different approaches. Smaller boats might need creative mounting solutions to maximize limited dashboard space, while larger vessels often require more complex integration with existing systems.
Fiberglass boats are generally the most straightforward for installation, while aluminum boats require special considerations for grounding and electrical isolation. Older boats might need electrical system upgrades to safely handle modern electronics loads.
Before starting any installation, we thoroughly assess your vessel’s electrical system, available space, and structural requirements. Some boats need additional prep work or modifications to properly support new electronics, and we’ll discuss all requirements upfront so there are no surprises.
Yes, we provide a comprehensive warranty on all installation work, separate from the manufacturer’s warranty on the electronics themselves. Our installation warranty covers workmanship, wiring, connections, and mounting for a full year from completion.
This means if you experience any issues related to our installation—loose connections, water intrusion at mount points, or wiring problems—we’ll fix it at no charge. The manufacturer’s warranty covers the electronics themselves, while our warranty ensures the installation work meets professional standards.
We also provide ongoing support if you have questions about operating your new electronics or need help with settings and configurations. Many boat owners find marine electronics intimidating at first, and we’re always available to help you get the most from your investment.
We work with all major marine electronics brands including Garmin, Raymarine, Lowrance, Simrad, and Furuno. Each brand has specific strengths, and we recommend systems based on your boating style, budget, and integration requirements rather than pushing any particular manufacturer.
Garmin tends to offer the most user-friendly interfaces and excellent GPS accuracy. Raymarine provides outstanding radar and autopilot integration. Lowrance and Simrad excel in fishfinding technology. Furuno builds bulletproof commercial-grade electronics for serious offshore use.
The key is matching the right equipment to your specific needs and ensuring everything integrates properly. We can also work with electronics you’ve already purchased, though we always recommend discussing equipment choices before you buy to ensure compatibility and optimal performance.
Water damage prevention starts with proper planning and marine-grade materials throughout the installation. We use only waterproof connectors, marine-grade sealants, and proper cable routing to keep water away from sensitive electronics and connections.
Every penetration through the hull, deck, or cabin is sealed with appropriate marine sealants and backing plates where necessary. We avoid running wires through areas prone to water accumulation and always provide proper drip loops to direct water away from connections.
All wire connections are made with heat-shrink tubing and marine-grade terminals designed for the saltwater environment. We also test every seal and connection before considering the job complete. Proper installation techniques prevent the water intrusion that destroys so many marine electronics installations over time.
