Our approach combines technical expertise with the discretion and professionalism that matches the caliber of vessels we work on. Whether you’re upgrading navigation systems on your yacht or installing custom audio integration, we treat every project with the precision your investment deserves.
The New Suffolk marine community knows the challenges of Long Island waters—from navigating busy harbors to finding fish in changing conditions. Local expertise matters when your electronics need to perform reliably in these specific environments.
The installation begins with understanding exactly what you need your marine electronics to accomplish. No generic solutions or one-size-fits-all approaches—each system is designed around how you actually use your vessel.
Next comes precise installation planning. Wire routing is mapped to avoid interference, mounting locations are selected for optimal performance and aesthetics, and integration points with existing systems are identified. This planning phase prevents the callbacks and rework that plague many marine electronics projects.
Installation follows ABYC standards with marine-grade connections, proper gauge wiring, and appropriate fusing throughout. Each connection is made to resist the corrosion and vibration that destroy poorly installed systems. Testing ensures everything functions correctly before the project is considered complete.
Finally, you receive a walkthrough of your new systems. No confusing manuals or guesswork—you’ll understand how to operate your equipment and get the most from your investment.

Marine electronics installation covers the full spectrum of onboard systems that make your time on the water more productive and enjoyable. Navigation and GPS systems provide accurate positioning and route planning for safe passage through Long Island’s busy waterways and harbors.
Fishfinder and sonar installation transforms your fishing success with advanced transducer placement and system integration. Custom marine audio systems deliver high-quality sound throughout your vessel with weather-resistant components designed for the marine environment.
Custom wiring and electrical work ensures your systems have clean power delivery and proper grounding. This foundation work prevents the electrical issues that cause expensive equipment failures and intermittent problems. For New Suffolk boat owners, this means systems that perform reliably whether you’re day fishing in Peconic Bay or making longer runs to Montauk.
The marine environment demands specialized knowledge. Salt air, vibration, and temperature changes destroy standard automotive-grade installations. Professional marine electronics installation uses components and techniques specifically designed for these harsh conditions.
Installation timeframes depend on the complexity of your system and the specific equipment being installed. A basic GPS chartplotter might be completed in a day, while comprehensive electronics packages with multiple displays, radar, and custom audio integration typically require 2-4 days.
The key difference is proper planning and scheduling. Many boat owners experience frustration with installers who provide vague timeframes or miss promised completion dates. Professional installation includes clear project timelines established upfront, so you know exactly when your vessel will be ready.
Complex installations like complete electronics refits or custom dashboard fabrication may require longer timeframes, but you’ll have a detailed schedule before work begins. This prevents the common industry problem of projects dragging on for weeks without clear completion dates.
Professional installation goes far beyond simply mounting equipment and connecting wires. It includes proper system design, marine-grade wiring with appropriate gauge selection, corrosion-resistant connections, and integration with existing vessel systems.
ABYC-compliant electrical work ensures your installation meets safety standards and won’t create hazards. This includes proper fusing, grounding, and wire routing that protects against chafing and interference. Many installation problems stem from cutting corners on these fundamental requirements.
System integration ensures your new electronics work seamlessly with existing equipment. This might include connecting your GPS to your VHF radio for DSC functionality, integrating your fishfinder with your chartplotter, or setting up NMEA networks for data sharing between devices. Professional installation also includes system testing and user training so you understand how to operate your equipment effectively.
Most marine electronics failures stem from poor installation practices rather than equipment defects. Common problems include undersized wiring, improper connections that corrode in the marine environment, and inadequate fusing that leads to electrical issues.
Rushed installations often skip critical steps like proper wire routing and strain relief. Vibration and movement eventually cause these connections to fail, leading to intermittent operation that’s difficult to diagnose. Salt air accelerates corrosion in connections that aren’t properly sealed or made with marine-grade materials.
Another frequent issue is inadequate system planning. When installers don’t understand how different components need to work together, you end up with systems that don’t integrate properly or perform below their potential. Professional installation addresses these issues upfront with proper planning, quality materials, and installation techniques designed for the marine environment.
The right marine electronics depend on how you use your vessel and what you want to accomplish on the water. Navigation systems should match your typical cruising area—basic GPS units work for coastal cruising, while offshore fishing requires more sophisticated chartplotters with radar integration.
Fishfinder selection depends on your fishing style and target species. Traditional 2D sonar works well for basic fish finding, while serious anglers benefit from CHIRP technology, side-scan imaging, and forward-facing sonar systems. Water depth in your fishing areas also influences transducer selection and power requirements.
Audio systems need to balance sound quality with marine durability. Consider how many zones you want to control, whether you need Bluetooth connectivity, and integration with your navigation systems. Professional consultation helps match equipment capabilities with your actual needs rather than overselling features you won’t use or underselling capabilities you’ll wish you had.
Properly installed marine electronics require minimal maintenance, but regular attention keeps them performing optimally. Connections should be inspected annually for corrosion, especially in salt water environments. Cleaning terminals and applying dielectric grease prevent many electrical problems.
Software updates are increasingly important as marine electronics become more sophisticated. Many units can update automatically when connected to WiFi, while others require manual updates. Keeping firmware current ensures you have the latest features and bug fixes.
Physical cleaning matters too. Salt spray and marine growth can affect antenna performance and screen visibility. Regular freshwater rinses and appropriate cleaning products keep equipment functioning properly. Transducers need periodic inspection to ensure they’re clean and properly aligned for optimal sonar performance.
Marine electronics can be installed on virtually any vessel, but installation approaches vary significantly based on boat type, size, and construction. Small boats might use portable or bracket-mounted units, while larger vessels typically require flush-mounted installations with custom wiring.
Fiberglass boats offer the most flexibility for installation, while aluminum boats require special considerations for grounding and through-hull installations. Wooden boats need careful attention to moisture protection and may require different mounting techniques.
Power requirements also vary by vessel. Smaller boats might run everything off a single battery, while larger vessels need dedicated electronics batteries and charging systems. Professional installation ensures your boat’s electrical system can support your electronics package without compromising engine starting or other critical systems. The key is matching the installation approach to your specific vessel and electrical system capabilities.
