VDO SingleViu 100mm (4") Tachometer - 5000 RPM

The VDO SingleViu 100mm (4") Tachometer - 5000 RPM is the standard instrument every serious boater and angler needs at the helm. Whether you're running a center console, sportfisher, or offshore rig, accurate engine RPM monitoring is non-negotiable for fuel efficiency, safety, and engine longevity. This tachometer delivers real-time engine speed feedback so you can maintain optimal RPM for cruising, trolling, or wide-open throttle performance without guesswork.

Built by VDO—a trusted name in marine instrumentation—this gauge features a 100mm (4-inch) dial face with a 5000 RPM maximum range, ideal for most inboard and outboard engines in recreational and light commercial use. The SingleViu design integrates seamlessly into standard dash installations, offering crisp analog readability even in direct sunlight and rough sea conditions. The robust construction and reliable stepper motor mechanism ensure consistent, lag-free needle response, so you can trust the reading every time you advance the throttle.

This tachometer works best with engines equipped with electronic ignition systems or pulse-output fuel injectors, making it compatible with most modern powerplants manufactured in the last 15+ years. Installation requires a tachometer signal wire from your engine and standard 12V power—straightforward enough for most boat owners, though professional installation is always recommended. Whether you're managing a tight troll for stripers and tarpon or pushing fuel economy on a long offshore haul, the VDO SingleViu 100mm Tachometer keeps you informed and in control.
