Pricing is the first question most boat owners ask, and it’s the hardest to answer with a single number. The cost of a marine electronics installation depends on the equipment, the boat, the scope of work, and the condition of the existing wiring and infrastructure. A simple fish finder swap on a bay boat and a full helm rebuild on a 42-foot sportfish are completely different projects.
At Chart House Marine Electronics, we provide detailed, line-item estimates after an in-person or phone consultation. But here’s a realistic breakdown of what to expect across common project types.
Single Device Installs
Adding a standalone chartplotter, fish finder, or VHF radio to an existing setup is the simplest type of job. Equipment cost varies by brand and model, and labor typically runs $300 to $800 depending on mounting complexity and wiring requirements. A flush-mount install in a pre-cut panel is straightforward. A custom panel fabrication or dashboard modification adds time and cost.
Radar Installations
A dome radar install on a center console T-top typically runs $2,500 to $5,000 total, including the scanner, cabling, mounting hardware, and labor. Open array radar systems for larger boats start around $5,000 and can exceed $10,000 depending on the unit and the mounting structure required. Radar installations involve running cable from the scanner to the helm, configuring the display, and tuning the system on the water.
Complete Helm Upgrades
A full helm replacement involves new multifunction displays, radar, sonar, GPS, VHF, AIS, autopilot, and networking. On a center console, this typically falls in the $10,000 to $25,000 range. On a larger sportfish or yacht with multiple helm stations, tower displays, and complex autopilot systems, the number can reach $30,000 to $60,000 or more.
The equipment itself accounts for the majority of the cost. Labor for a complete helm rebuild typically runs $2,000 to $8,000 depending on boat size and complexity. Panel fabrication, rewiring, and NMEA 2000 backbone installation are included in that labor figure.
Trolling Motor and Sonar Systems
A professional trolling motor installation with network integration runs $1,500 to $4,000 depending on the motor, battery setup, and wiring complexity. Adding a live sonar system like Garmin Panoptix LiveScope with a dedicated display adds another $2,500 to $5,000.
Audio and Entertainment
Marine audio systems range from basic setups with a head unit and a couple speakers ($800 to $2,000) to full entertainment packages with multiple zones, subwoofers, amplifiers, and streaming capabilities ($3,000 to $10,000+). Chart House installs marine entertainment systems that are built for the saltwater environment and wired to perform without interference from other electronics.
What Drives Cost Up
Several factors increase the cost of an installation beyond the equipment price. Older boats with deteriorated wiring need rewiring before new equipment goes in. Custom panel fabrication for non-standard helm layouts adds time. Boats with limited access behind the dash or through the hardtop require more creative cable routing. Autopilot installations on hydraulic steering systems involve plumbing work that adds labor hours.
What to Ask Your Installer
Get a written estimate that separates equipment cost from labor. Ask whether wiring and panel work are included. Confirm that sea trial testing and calibration are part of the scope. Make sure the estimate covers all necessary cables, connectors, and mounting hardware.
