Marine Gauges & Displays
Marine Gauges, Engine Displays, Instrument Panels, Senders & Helm Electronics
Shop marine gauges and displays for engine monitoring, helm upgrades, replacement dash parts, fuel level, speed, RPM, voltage, oil pressure, water temperature, trim, depth, hour tracking, senders, bezels, wiring, and instrument-panel service.
Fitment Check
Ask Parts Desk
Confirm gauge diameter, voltage, sender range, engine type, display protocol, dash opening, connector style, and wiring before ordering.
A good helm setup depends on matching the display, sender, wiring, power supply, and engine or tank signal.
Find Gauges Faster
Search by Gauge Type, Diameter, Sender Range, Engine Brand, or Part Number
Marine gauges can look similar while using different signal ranges, sender types, lens styles, bezels, connectors, and dash sizes. Search by exact part number when possible.

12V SystemsMost recreational boats use 12V gauge power and lighting circuits
24V SystemsLarger boats may need compatible 24V gauges, displays, and lighting
Analog Gauges & Senders
Match the Gauge to the Signal
Analog gauges depend on compatible senders, wiring, grounds, lighting, and dash openings. Fuel, oil pressure, temperature, trim, and tachometer readings can be inaccurate when the sender range or signal type does not match.
Digital Displays & Networks
Connect Engine Data, Navigation, and Helm Monitoring
Digital displays may use NMEA 2000, engine gateways, proprietary engine networks, GPS, transducers, or chartplotter integration. Confirm compatibility with the engine, sensors, network backbone, and display size.
01
Measure the Dash Opening
Confirm gauge diameter, mounting depth, bezel clearance, and panel thickness before replacing an instrument.
02
Check the Sender
A new gauge may still read incorrectly if the tank, trim, temperature, or pressure sender is worn or mismatched.
03
Protect the Circuit
Clean grounds, proper fusing, sealed terminals, and marine wiring help keep gauges stable and readable.
Replacement Guidance
Before You Replace a Gauge, Check the Whole Signal Path
For the best match, search by part number or brand first. If you are not sure, send the Parts Desk photos of the gauge face, back of the gauge, wiring, sender, dash opening, and the engine or tank details.
Replacing one gaugeMatch diameter, signal type, voltage, lighting, bezel style, connector layout, and sender compatibility.
Replacing a gauge setPlan the whole dash so the gauge style, lighting color, face color, and sizes look consistent.
Troubleshooting readingsCheck grounds, power, sender resistance, connectors, corrosion, and wiring before assuming the gauge is bad.

Gauges & Displays FAQ
Choosing Marine Gauges and Displays
How do I choose the right replacement marine gauge?
Match the gauge diameter, voltage, sender range, signal type, dash opening, connector style, lighting, and face style. Use the old part number when possible.
Why does my gauge read incorrectly?
Incorrect readings can come from a bad sender, wrong sender range, poor ground, damaged wiring, corrosion, loose terminals, or an incompatible gauge.
Can I replace analog gauges with a digital display?
Sometimes. It depends on the engine, available data output, sender setup, network type, gateway availability, and the display you want to use.
Can the Parts Desk help match gauges and senders?
Yes. Send photos of the gauge front and back, sender, wiring, dash opening, engine model, and any part numbers you can find.
