Marine Electronics Diagnostics

Marine electronics diagnostics is a systematic evaluation of an onboard system’s power distribution, wiring integrity, signal strength and data communication. It includes software and firmware checks, performance testing under simulated load, and, when possible, on-water trials to pinpoint faults or degraded operation.

Diagnostics cover chartplotters and multifunction displays, radar and fish finders, autopilot and steering controls, VHF/DSC and satellite communication units, networked sensors and cameras, navigation lighting circuits, and any other electronic component installed on the vessel.

The process begins with a visual inspection of wiring, connectors and mounting points. Power and ground connections are then verified using marine-grade test equipment. Firmware and software versions are reviewed, communication protocols are tested for data integrity, signal levels are measured, and final validation is performed—ideally during an on-water trial to confirm real-world performance.

Duration depends on system complexity and vessel size. A standalone display or radio inspection usually takes one to two hours, whereas a fully integrated suite involving multiple devices and network segments can require half a day or more. An upfront estimate is provided before work begins.

Yes. Upon completion you’ll receive a detailed report outlining identified issues, measurement data and prioritized recommendations for repair, calibration or component replacement. This document serves as the foundation for any follow-on work orders.

After diagnostics, a scope of work is prepared that details the necessary repairs or replacements along with time and cost estimates. No further work proceeds without your approval, ensuring full transparency and alignment with your vessel’s operational needs.
