Part of the Amega black-dial instrument line that has been in production since 1986, this gauge pairs a black dial face with red graduations, white numerals, and a vivid white pointer staff for clear at-a-glance readability from the helm, day or night, thanks to through-dial and perimeter lighting.\u003c\/p\u003e\u003cp\u003eThe face is protected by a scratch resistant curved glass lens set into a black, near-flush bezel with an outer diameter of 2.39 inches, giving it a low-profile, integrated look on the dash. The dial carries both U.S. And metric scales with ISO symbols where applicable, so it reads correctly regardless of which measurement standard the rest of the helm uses. Electrically, the gauge draws 0.10 to 0.15 amps and requires a sender with Sierra sender code \"D\" to display accurate readings; it uses NPT thread styling at the sender connection.\u003c\/p\u003e\u003cp\u003eThis gauge is designed to work as a standalone instrument or as part of a matched Amega instrument set alongside the tachometer\/hour meter and other companion gauges, so multiple gauges on the same dash share a consistent black-dial look.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 57904P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Temperature Gauge (Amega, 2 inch, I\/O-IB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Range:\u003c\/strong\u003e 120 to 240 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Size:\u003c\/strong\u003e 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel Outer Diameter:\u003c\/strong\u003e 2.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Color:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduations:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumerals:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePointer:\u003c\/strong\u003e White pointer staff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens:\u003c\/strong\u003e Scratch resistant curved glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel Finish:\u003c\/strong\u003e Black, near-flush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Markings:\u003c\/strong\u003e U.S. And metric scales with ISO symbols where appropriate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Draw:\u003c\/strong\u003e 0.10 to 0.15 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSender Code Required:\u003c\/strong\u003e D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat temperature range does the Sierra 57904P gauge read?\u003c\/strong\u003e The Sierra 57904P Amega water temperature gauge reads from 120 to 240 degrees Fahrenheit across its 2 inch dial.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat sender does the 57904P need to work correctly?\u003c\/strong\u003e This gauge requires a sender with Sierra sender code \"D\" for accurate temperature readings;
