Veratron ViewLine 52mm Oil Pressure Gauge 80 PSI/5 Bar, Black Dial

Veratron built the ViewLine series to give you clean, honest engine monitoring without turning your dash into a science project. This 52mm oil pressure gauge is one piece of that modular family, and it does exactly one job well. It shows you what your engine's oil pressure is doing, at a glance, from the helm.

The face is a black dial with a matching round bezel, and it reads from 0 to 80 PSI (5 Bar). If you're building out a full ViewLine cluster, that's the whole point of the line. Every gauge shares the same look, so your oil pressure, water temp, voltmeter, and tach all sit together as a matched set instead of a mismatched grab bag. The bezel is interchangeable too, so if you ever want to swap dial colors down the road, you're not buying a whole new gauge.

Boaters reach for these for two reasons. Either you're repowering and want fresh instruments that match the new engine, or you're tired of squinting at a faded old gauge and want something that reads clean day and night. Both are good reasons. The ViewLine platform is meant to grow with you, so starting with the oil pressure gauge and adding to the cluster later is a perfectly sane way to do it.

Readability is where these earn their keep. The dial is easy to pick up in bright sun, and there's a red LED warning light built in that trips on both the high and low side, so you get a heads-up before a pressure problem turns into an engine problem. An anti-fog double lens keeps the face clear, which matters more than you'd think on an open helm that sees temperature swings and spray.

Electrically, it's easy to live with. It runs on anything from 8 to 32 volts, so it drops into a 12V or 24V system without fuss. There's reverse polarity protection built in, which has saved more than one rushed install from a wiring mistake. The connection is an 8-pole Tyco/Hirschmann MQS plug, and the front carries an IP67 protection rating, so a wet dash isn't a problem.

A couple of install notes from real boats. The gauge wants a 52mm (2-1/16") mounting hole, and it needs about 50mm of depth behind the dash, so check your clearance before you cut, especially on a tight sailboat panel where wiring already lives back there. Ground it straight to the battery negative, not to a shared panel ground. We've seen needles bounce underway when the ground is shared with a bilge pump or other loads, and a clean ground fixes it every time. And use the supplied rubber seal. On exposed helms, skipping the gasket is the number one cause of a lens fogging up a season or two down the line.

For accuracy, the gauge reads a standard resistive (ohm) sender. Pair it with the matching Veratron oil pressure sender rated for this range, and mount that sender on the engine block rather than on a remote line, and you'll get a reading you can trust all the way up to 80 PSI. A mismatched sender is the usual reason a gauge reads a few PSI high, so this is worth getting right.

If you're running more than one ViewLine gauge, they play nicely together. You can share a single harness across the cluster, and the backlighting ties into your dimmer circuit so the whole panel dims together at night. Just wire the backlight consistently across the gauges so you don't end up with one bright gauge fighting the rest.

In the box you get the gauge, a connection cable, the round bezel, a rubber seal, a spinlock mounting clamp, and the installation and safety instructions. It's a straightforward afternoon install for anyone comfortable behind the dash, and it's the natural choice when you want a clean, matched instrument panel at a price that makes sense.
