Faria Euro Black 4" Tachometer, 4000 RPM Diesel Mechanical Take-Off
Faria Euro Black 4" Tachometer, 4000 RPM Diesel Mechanical Take-Off — Product description
The Faria Euro Black 4" Tachometer is a 4,000 RPM diesel gauge built for mechanical take-off and variable ratio alternator setups. Perimeter-lit black dial, bold white numbers, black aluminum bezel. It drops into a standard 3-3/8 inch helm cutout and reads clean day or night.
The Faria Euro Black 4" Tachometer keeps an honest eye on your diesel's RPM, and it does it the simple, reliable way. This is a 4,000 RPM gauge wired for a mechanical take-off sender or a variable ratio alternator signal, which covers the vast majority of small and mid-size marine diesels. If your engine spins a mechanical tach cable off the front of the crank, or you're pulling your signal from the alternator, this is the gauge that matches.
The face is pure Euro Black. A perimeter-lit black dial, bold white graphics, a black aluminum bezel, and a contoured white pointer under a flat glass lens. It reads clean in bright sun and it reads clean at 2 a.m. on a long passage. The 4-inch dial gives you big, legible numbers without hogging the whole panel, and it drops into a standard 3-3/8 inch (85mm) cutout, so it swaps straight into most existing helm holes.
Who's this for? Sailors with a diesel auxiliary. Trawler owners. Anyone running a single or twin diesel who wants a matching Euro Black gauge set at the helm. The 12/24 VDC range means it works on both common house voltages, so you're covered whether your boat is a 12-volt weekender or a 24-volt cruiser.
One thing to get right before you buy: the signal type. This gauge is built for diesel engines using a mechanical take-off or a variable ratio alternator. It isn't the magnetic pick-up version, and it isn't a gas-engine tach. If your diesel uses a magnetic pickup sender, or you're running a gas engine, you'll want a different Faria tach. Match the signal source to the gauge and calibration is straightforward. Get it wrong and the needle won't track.
Speaking of calibration, on the variable ratio alternator setup you set the gauge to your alternator's pulley ratio. Do that before your first run. Set it right and the tach tracks true across the whole band. Skip it and you'll read low up top. It's a quick job with the adjustment on the back of the gauge, and once it's dialed in you don't touch it again.
Faria Beede has been building marine instruments for over 50 years, and this gauge shows it. Sealed against the weather, vibration-tolerant, and simple to wire. No CANbus, no software, no menus. Power, ground, light, signal, and sender. If you can run a few wires, you can install this gauge in an afternoon and be reading accurate RPM by dinner.
Building or refreshing a helm? This tach pairs with the rest of the Faria Euro Black line, so your speedometer, fuel, and voltage gauges all share the same black face and white graphics. A clean, consistent panel isn't just good looks. When every gauge shares the same layout and lighting, your eyes learn where to look, and a quick scan tells you everything's normal without you having to think about it.
Installation is old-school in the best way. The gauge mounts from the front into a 3-3/8 inch hole and clamps from behind with a bracket and studs. Wiring is basic 12/24-volt: switched power, a good ground, the dash light feed, and the signal line from your take-off or alternator. For diesels with a mechanical take-off, run the sender cable with gentle bends and keep it clear of tight kinks near the engine mounts, which keeps the drive turning smooth and the reading steady.
Bottom line, it's a straightforward, good-looking diesel tach from a name that's been doing this for half a century. Get the signal type right, set the ratio, and you've got accurate RPM at a glance for years. That's all most of us want out of a tach.

Frequently asked questions
What engines is this tachometer for?
It's built for diesel engines running a mechanical take-off sender or a variable ratio alternator signal, with a 4,000 RPM range that suits most small and mid-size marine diesels. It isn't a gas-engine tach.
Will it work with a magnetic pickup sender?
No. This is the mechanical take-off and variable ratio alternator version. If your diesel uses a magnetic pickup, you'll need the magnetic pick-up model instead, so check your sender type before ordering.
What size mounting hole does it need?
A standard 3-3/8 inch (85mm) cutout. The 4-inch gauge drops straight into most existing helm holes and clamps from behind with a bracket.
Does it work on a 24-volt system?
Yes. It runs on 12 or 24 VDC, so it fits both common marine house voltages without any extra adapters.
Does this tachometer have an hourmeter?
No, this model is tachometer only. If you want engine hours tracked on the same gauge, Faria makes a separate Euro Black version with a built-in hourmeter.
How do I calibrate it?
On the variable ratio alternator setup you set the gauge to your alternator's pulley ratio using the adjustment on the back. Do it before your first run and the tach tracks true across the whole band.
Can I use it on a gasoline engine?
No, it's a diesel tachometer. A gas engine uses a different signal source, so you'd want a gas-rated Faria tach for that application.
How is it wired and mounted?
It front-mounts into a 3-3/8 inch hole and clamps from the rear. Wiring is basic 12/24-volt: switched power, ground, the dash light feed, and the signal line from your take-off or alternator.
Will it match my other Faria Euro Black gauges?
Yes. It shares the Euro Black black dial with white graphics and black aluminum bezel, so it lines up cleanly alongside the rest of the Faria Euro Black instrument line.
