VDO Gauges

VDO brings a long instrument heritage to marine gauges, and this collection covers their lineup of tachometers, speedometers, fuel, temperature, voltmeters, and hourmeters across series like Cockpit, Marine, Viewline, and Allentare. Building a clean helm comes down to staying within one series, picking the right sizes, and pairing each gauge with the correct sender.

Pick a VDO series for a matched look

VDO offers several gauge families, each with its own dial face, bezel, and lighting. Cockpit and Marine series cover the practical workhorse gauges, while Viewline brings a modern look and Allentare adds a teak-trimmed style. Choose one series and use it across every gauge so the helm reads as a finished set rather than a mismatch.

Size the gauges to the job

The primary gauges, tachometer and speedometer, are usually 85mm (3-3/8 inch) so they read fast at a glance. The support gauges, fuel, temperature, voltmeter, and hourmeter, are typically 52mm (2-1/16 inch) grouped around them. Measure your dash cutouts before ordering, since changing a hole size means cutting the dash.

Match senders to the gauges

An analog gauge reads true only with the matching sender and resistance range. VDO offers fuel level, temperature, and pressure senders designed to drive their gauges, so pair each gauge with the correct sender and confirm the thread and fitting suit your tank or engine. The wrong sender resistance gives a needle that reads high, low, or sits dead.

Speedometer and tach choices

VDO speedometers come in pitot-pressure and GPS styles. A pitot speedo reads off water pressure and needs a clean pickup, while a GPS speedometer reads true speed over ground with no pickup to clog, which many builders now prefer. Tachometers need the correct signal input for your engine, so confirm the engine type before choosing a tach.

Lighting and finish

Match the dial color and bezel finish to your console, and confirm the gauges share the same backlighting so the helm glows evenly at night. A consistent look and even lighting are what make a dash look professionally done.
