White face, orange-tipped pointer, and red thru-dial with white perimeter lighting for 12 volt night runs. Ships with fittings and 20 feet of tubing, IP65 rated for helm spray.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSierra's Lido water pressure gauge kit gives you a clear, direct read on your engine's cooling water pressure, and that's one of the most useful numbers you can have at the helm. When your water pressure holds steady, your cooling system is doing its job. When it drops, you get a warning before the temperature gauge ever moves. This 2-inch gauge reads 0 to 30 PSI on a full-sweep mechanical movement, so the whole face is working for you instead of cramming the scale into a tiny arc.\u003c\/p\u003e\n\u003cp\u003eHere's why water pressure matters on an outboard or inboard. Your engine pulls raw water in through the lower unit or a thru-hull, pushes it through the block, and spits it back out. A worn impeller, a clogged intake screen, a plastic bag sucked against the pickup, any of these will cut your flow. A temperature gauge tells you the engine is already hot. A pressure gauge tells you the flow dropped a few minutes earlier, while you still have time to back off the throttle and check things out. That head start is the whole point.\u003c\/p\u003e\n\u003cp\u003eThe face is white with a black pointer tipped in orange, which reads fast in direct sun. You glance, you know, you go back to driving. At night the gauge lights up with a red thru-dial glow and a white perimeter ring, both running on 12 volt DC off your existing panel lighting circuit. The red thru-dial keeps your night vision intact while the white ring makes the numbers pop. One note from the folks who run small battery banks: the white perimeter LEDs do pull a little current, so if you're on a tight house bank overnight, that's worth knowing.\u003c\/p\u003e\n\u003cp\u003eThe bezel is polished stainless steel, which looks sharp against a white or black dash. Fair warning for saltwater boats, that polish will pit if you never touch it. A quick wipe and an occasional polish keeps it bright. The gauge carries an IP65 rating, so it shrugs off spray and washdown at the helm, but IP65 is splash and jet protection, not full submersion, so it belongs behind a console or on a protected dash, not out on an open swim platform.\u003c\/p\u003e\n\u003cp\u003eThe kit ships with fittings and a full 20 feet of tubing, which is enough to run from a transom-mounted engine all the way to a center console dash on most boats in the 25 to 35 foot range. On a smaller skiff you'll have plenty to spare. On a big cruiser you may come up short, and boaters in that spot usually splice in a brass union to extend the run. When you route the line, take your time through tight bilge spaces. The tubing can kink if you yank it around a sharp corner, so pre-bend it gently and support it along the way.\u003c\/p\u003e\n\u003cp\u003eBecause the movement is mechanical, the gauge reads pressure straight off the line, no electronic sender to fail. The only electrical connection is the 12 volt lighting. That simplicity is a big part of why these hold up. If the pointer ever sticks or reads erratic right after install, it's almost always trapped air in the line. Bleed the air, tap the gauge lightly, and the full-sweep pointer settles down.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anybody running an outboard or a smaller inboard who wants real-time cooling feedback instead of waiting for the temp alarm. It's a favorite on center consoles, bay boats, and repowers where the old gauge cluster didn't include water pressure. Who's it not for? High-pressure systems well above 30 PSI, and anyone needing a fully submersible gauge. Match the range to your engine and you'll get years out of it.\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 diameter face fits standard marine dash cutouts and gauge clusters\u003c\/li\u003e\n  \u003cli\u003e0 to 30 PSI range covers cooling water pressure on outboards and small inboards\u003c\/li\u003e\n  \u003cli\u003eFull-sweep mechanical movement spreads the scale across the whole face for a quick, precise read\u003c\/li\u003e\n  \u003cli\u003eWhite face with a black, orange-tipped pointer stays readable in direct sun\u003c\/li\u003e\n  \u003cli\u003eRed thru-dial and white perimeter lighting run on 12 volt DC for clear night visibility\u003c\/li\u003e\n  \u003cli\u003ePolished stainless steel bezel resists corrosion and looks sharp on any dash\u003c\/li\u003e\n  \u003cli\u003eIP65 rating protects against helm spray and washdown\u003c\/li\u003e\n  \u003cli\u003e20 feet of tubing included, enough to reach the dash on most 25 to 35 foot boats\u003c\/li\u003e\n  \u003cli\u003eFittings included so you can plumb the line without a separate parts run\u003c\/li\u003e\n  \u003cli\u003eMechanical movement reads straight off the line, no electronic sender to fail\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 this gauge measure?\u003c\/summary\u003e\n    \u003cp\u003eIt reads your engine's cooling water pressure.
