It uses a domed, scratch resistant lens over a 3 inch gauge face, reading from 0 to 50 mph, and is constructed from glass and plastic for durability in a marine helm environment. As a pitot type speedometer, it works with a pitot tube pickup mounted on the transom or hull that senses water pressure created by boat speed and translates that pressure into a needle reading on the gauge face, giving a direct mechanical speed reading without relying on a paddlewheel sensor.\u003c\/p\u003e\u003cp\u003eThis gauge is sold as part of the Amega series from Sierra, a brand that has supplied engine and drive parts to the marine industry for decades, with products engineered to meet or exceed the equipment they are designed to work with. The 3 inch size and domed lens make it a straightforward panel-mount upgrade or replacement for boaters standardizing their helm gauges on a matching Amega set, and the scratch resistant lens helps the face stay legible after years of sun, spray, and cleaning.\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 57898P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Pitot type speedometer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Size:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed Range:\u003c\/strong\u003e 0 to 50 mph\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens:\u003c\/strong\u003e Domed, scratch resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Glass, plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 8 x 8 x 4.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 10.2 cm L x 17.3 cm W x 19.3 cm H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 731957420046\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00731957420046\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat type of speedometer is the Sierra 57898P?\u003c\/strong\u003e The Sierra 57898P Amega speedometer is a pitot type gauge, meaning it reads boat speed from water pressure sensed by a pitot tube pickup rather than a paddlewheel sensor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat speed range does this gauge read?\u003c\/strong\u003e It reads from 0 to 50 mph on a 3 inch gauge face, part of the Sierra Amega series (part number 57898P).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow big is the 57898P gauge face?\u003c\/strong\u003e The gauge face measures 3 inches, a common panel-mount size for boat helm speedometers in the Amega lineup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the lens made of and how durable is it?\u003c\/strong\u003e The 57898P uses a domed, scratch resistant lens over a glass and plastic gauge housing, designed to stay legible despite sun and spray exposure at the helm.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the overall dimensions of this speedometer?\u003c\/strong\u003e The Sierra 57898P measures 8 x 8 x 4.38 inches as an item, and ships in a package measuring 10.2 cm L x 17.3 cm W x 19.3 cm H.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 57898P speedometer weigh?\u003c\/strong\u003e This gauge weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a pitot tube included with the 57898P kit?\u003c\/strong\u003e The listing covers the Amega speedometer gauge itself (part number 57898P); it does not specify an included pitot tube pickup, so confirm your existing pitot tube setup is compatible before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brand makes the 57898P speedometer?\u003c\/strong\u003e The 57898P is a Sierra product, sold under Sierra's Amega gauge series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 57898P a genuine Sierra part or aftermarket?\u003c\/strong\u003e Yes, part number 57898P is a genuine Sierra Amega speedometer, not a third-party aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in the package?\u003c\/strong\u003e The Sierra 57898P ships as a single gauge, with a package quantity of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the 57898P speedometer manufactured?\u003c\/strong\u003e The Sierra 57898P is manufactured in the United States.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 57898P speedometer?\u003c\/strong\u003e The UPC for the Sierra 57898P Amega speedometer is 731957420046.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988448424155,"sku":"SIE-57898P","price":86.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/57898P.png?v=1784938557","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-57898p-amega-3-domed-pitot-speedometer-kit-50-mph-scratch-resistant-lens","provider":"Good Vibes Marina","version":"1.0","type":"link"}
