A white face, polished bezel, and black pointer with an orange tip keep it easy to read, and thru-dial plus perimeter lighting keeps it legible after dark. It wires into a standard 12-volt boat system.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eOil pressure is one of those numbers you want to be able to read without thinking about it. Glance down, see the needle sitting where it should, and get back to running the boat. That's the whole job of the Sierra 65501P. It's a 2-inch analog oil pressure gauge from the Lido series, and it reads from 0 to 80 PSI on a short electrical sweep movement built for the marine environment.\u003c\/p\u003e\n\u003cp\u003eThe Lido styling keeps things simple and legible. You get a white face, a polished bezel, and a black pointer with an orange tip that stands out against the dial. In daylight the contrast makes the reading easy to catch out of the corner of your eye. When the sun drops, thru-dial and perimeter lighting take over, so the gauge stays readable on a night run back to the ramp. It's a clean, honest instrument face with no clutter.\u003c\/p\u003e\n\u003cp\u003eUnder the bezel it's a short electrical sweep gauge. That means it works with a compatible oil pressure sending unit threaded into the engine, and the sender does the measuring while the gauge shows the result. The sending unit isn't included in the box, so if you're replacing an old gauge, match the new one to the sender already on your engine, or plan to fit the matching Sierra sender at the same time. Getting the gauge and sender paired correctly is what keeps the needle honest. A mismatched sender is the number one reason a new gauge reads high, low, or pegged.\u003c\/p\u003e\n\u003cp\u003eWiring is straightforward 12 Volt DC. The gauge lands in a standard 2-inch panel opening, and the housing is short front to back, which helps on tight center-console dashes where there isn't much room behind the panel for wire connectors. If you're building or refreshing a helm, that shallow depth is worth knowing about before you cut. One tip from the install crowd: tape the edges of the cutout while you seat the polished bezel so you don't scuff it during fit-up.\u003c\/p\u003e\n\u003cp\u003eThis version comes without a programmable warning indicator, so there's no built-in low-pressure alarm. That's not a downside for most boats. It just means the gauge does one thing and does it clearly. You watch the needle. If you want an audible alert, you'd add a separate monitoring device on the engine. For a lot of outboards and simpler inboard setups, a clean analog readout is exactly what you want at the helm.\u003c\/p\u003e\n\u003cp\u003eKeep in mind this is a 12 Volt DC gauge. If your boat runs a 24-volt house or start system, this isn't a direct drop-in without the right wiring, so check your system voltage before you order. On a standard 12-volt boat it wires in like any other analog gauge, and the lighting ties into your dash light circuit. For most trailer boats, bass boats, bay boats, and small cruisers, 12 volts is exactly what you've got, and this gauge is right at home.\u003c\/p\u003e\n\u003cp\u003eWho's it for? Anybody replacing a tired or fogged-up oil pressure gauge, or rigging a fresh helm on a center console, runabout, or small cruiser running a 12-volt system. Sierra builds this line to meet or exceed the original equipment part it replaces, and they supply a lot of the same parts to engine and boat builders, so you're getting a known quantity. It's an inexpensive part that tells you something important about your engine every time you look at it. That's a good trade.\u003c\/p\u003e\n\u003cp\u003eA couple of install notes worth repeating. The perimeter and thru-dial lighting pulls a little current, so wire it through your existing instrument light circuit rather than hanging it off something unswitched. And on an outboard console that vibrates hard, snug the mounting studs down properly so the gauge doesn't work loose over a season. None of it is complicated. It's a straightforward swap for anybody who's wired a gauge before, and not a bad first project if you haven't.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e2-inch analog dial with a short electrical sweep, easy to read at a glance from the helm\u003c\/li\u003e\n  \u003cli\u003eReads 0 to 80 PSI, covering the normal running range for most marine engines\u003c\/li\u003e\n  \u003cli\u003eWhite face, polished bezel, and a black pointer with an orange tip for fast, clear reading in daylight\u003c\/li\u003e\n  \u003cli\u003eThru-dial and perimeter lighting keep the dial legible on night runs\u003c\/li\u003e\n  \u003cli\u003e12 Volt DC, wires into a standard boat electrical system\u003c\/li\u003e\n  \u003cli\u003eShort electrical sweep movement pairs with a compatible oil pressure sending unit (sold separately)\u003c\/li\u003e\n  \u003cli\u003eNo programmable warning indicator, just a clean straightforward pressure readout\u003c\/li\u003e\n  \u003cli\u003eSierra part 65501P from the Lido series, built to meet or exceed the original equipment it replaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sierra Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the Sierra 65501P measure?\u003c\/summary\u003e\n    \u003cp\u003eIt reads engine oil pressure from 0 to 80 PSI on a 2-inch analog dial.
