Boat Wiring: Why Hire a Professional
Boat wiring isn’t automotive wiring. The marine environment is brutal — salt spray, vibration, humidity, and constant flexing eat through improperly chosen wire and connectors in months, not years.
Faulty wiring is a leading cause of onboard fires and electronics failures. Hiring a professional protects your boat, your warranty, and the people on board.

Installation Services
Single accessory installs to full vessel rewires — every job built to marine-grade standards.
Navigation, GPS & Sonar Electronics
Chartplotter and GPS installation and networking, fishfinder and HDS displays, transducer installation (thru-hull, transom, and shoot-thru), and AIS-capable VHF radio installation. Whether it’s a single MFD or a full multi-station network, we wire it clean and tune it before you leave the shop.
Marine Audio & Stereo Systems
Custom stereo source units, speakers, subwoofers, and amplifiers from Fusion, JL Audio, and Wet Sounds. We size the system to your boat, run proper power and grounds, and tune the install so it sounds as good underway as it does at the dock.
Power-Pole & Trolling Motor Installation
Authorized Power-Pole dealer — we install shallow water anchors, hydraulic setups, and dash-mounted controls so you can stop on a dime. Trolling motor wiring done right means the right gauge wire, the right batteries, and a charging system that actually keeps up.
Battery Banks, Pumps & Full Rewires
Bilge pump wiring and upgrades, battery bank and charging system installation, and complete boat rewires and harness repair. Whether you’re refitting an older hull or chasing a gremlin in a year-old boat, we’ll get the wiring right and document it so the next tech can read it at a glance.
