Professional Boat Electronics Installation Services

Your Electronics Work Right the First Time

You know the frustration of marine electronics that fail when you need them most. Half-finished installations, intermittent radar, audio systems that cut out mid-voyage.

That ends here. When we install your navigation systems, fishfinders, or custom audio integration, everything works as designed from day one. Your GPS coordinates are accurate, your sonar reads clearly at depth, and your entertainment systems deliver premium sound quality whether you’re anchored off Montauk or cruising the Sound.

The difference is in the details most installers skip. Proper marine-grade wiring, correct gauge selection, galvanic corrosion prevention, and complete system integration. Your investment in marine electronics actually delivers the performance and reliability you paid for.

Marine Electronics Installation Process

From Planning to Sea Trials

We start with a comprehensive assessment of your vessel and your specific needs. Whether you’re upgrading navigation systems, installing a complete audio package, or integrating fishfinders with your existing electronics, we map out the entire installation before touching a single wire.

Our technicians handle everything from custom dashboard fabrication to running marine-grade wiring through your boat’s infrastructure. We use proper mounting techniques, ensure all connections meet ABYC standards, and integrate new systems with your existing electronics seamlessly.

Before we consider the job complete, we conduct thorough sea trials to verify every system functions correctly under real conditions. Your navigation displays show accurate positioning, your audio systems deliver clear sound at all volume levels, and your fishfinder provides reliable readings at various depths and speeds.

How long does a typical marine electronics installation take?

Installation timeframes depend on the complexity of your project, but most single-system installations take 1-2 days. A basic GPS chartplotter and fishfinder combination typically requires one full day for proper installation and testing.

More comprehensive projects involving multiple systems, custom dashboard work, or complete electronics packages can take 3-5 days. We provide realistic timelines upfront and stick to them. Unlike many installers who give vague estimates, we schedule your project with specific start and completion dates.

The key is doing the installation correctly rather than quickly. Rushing marine electronics installation leads to the problems you’re trying to avoid – intermittent connections, system conflicts, and equipment failures when you need your electronics most.

Yes, we offer comprehensive mobile installation services throughout Shelter Island and the surrounding Long Island area. Our mobile service brings the same professional installation capabilities directly to your marina, dock, or boatyard.

Mobile installations are ideal for boat owners who prefer to keep their vessels at their home dock during the installation process. We arrive with all necessary tools, equipment, and materials to complete your installation on-site.

The only limitation is projects requiring extensive custom fabrication work, which we handle at our fully-equipped facility. However, the majority of marine electronics installations can be completed successfully using our mobile service, saving you the time and expense of transporting your boat.

We install and service all major marine electronics brands, with factory authorization for warranty work on Garmin, Raymarine, and Simrad systems. This includes their full product lines from basic fishfinders to advanced radar and navigation systems.

We also work with Furuno, Lowrance, Humminbird, and specialty marine audio brands. Our technicians maintain current certifications on the latest equipment, ensuring we can properly install and configure even the newest technology releases.

Being factory authorized means we can handle warranty repairs and software updates correctly. When you need service on your marine electronics, we have direct access to manufacturer support and genuine replacement parts. This eliminates the delays and complications that often occur with unauthorized service providers.

Integration is one of our specialties, and it’s often more complex than boat owners realize. Modern marine electronics use NMEA networking protocols that allow different systems to share information, but proper configuration requires specific technical knowledge.

We can integrate new navigation equipment with existing autopilot systems, connect fishfinders to chartplotters for overlay displays, and link VHF radios to GPS systems for DSC functionality. The goal is creating a unified system where all your electronics work together seamlessly.

Before starting any integration project, we assess your current systems’ compatibility and explain exactly what functionality you’ll gain. Some older equipment may have limitations, and we’ll be upfront about what’s possible versus what would require system upgrades.

Waterproofing and reliability start with using proper marine-grade components and following ABYC electrical standards throughout the installation. We use tinned copper wire, marine-grade connectors, and appropriate sealants for every connection point.

All through-hull penetrations receive proper sealing with marine sealants rated for below-waterline use. Cable routing avoids areas where water accumulation is likely, and we install proper drip loops to direct any moisture away from connection points.

Every installation includes comprehensive testing under various conditions before we consider the job complete. We verify all systems function correctly in wet conditions, check for any voltage drops under load, and ensure all connections remain secure when subjected to normal boat movement and vibration.

Our installation work comes with a comprehensive one-year warranty covering all labor and any installation-specific components we provide. This includes wiring, connectors, mounting hardware, and custom fabrication work.

Equipment warranties are handled directly through the manufacturers, and our factory authorization means we can perform warranty service efficiently. If any installation-related issues occur, we return to resolve them at no charge during the warranty period.

We also provide detailed documentation of your installation, including wiring diagrams and system configuration notes. This information proves invaluable for future service work or system expansions, and it’s something many installers skip but that adds significant value to your investment.
