It reads boat speed across a 20-80 MPH range and features a domed, scratch resistant lens that protects the dial face from fogging, glare, and everyday wear at the helm. As part of Sierra's Amega gauge line, it is designed to give a clear, accurate speed readout while standing up to the vibration, sun exposure, and moisture common in a marine helm environment.\u003c\/p\u003e\u003cp\u003eThis kit uses a pitot tube for its speed input, meaning boat speed is measured directly from water pressure at the hull rather than through an engine sensor, making it a straightforward add or replacement for boats already set up with (or being fitted for) a pitot-type speed sensor. The domed face improves visibility and helps resist scratching compared to a flat lens, keeping the gauge legible over years of use.\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 57899P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Speedometer, Pitot Type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Style:\u003c\/strong\u003e Domed, Scratch Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Size:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed Range:\u003c\/strong\u003e 20-80 MPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type:\u003c\/strong\u003e Pitot Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 8 x 8 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 731957420244\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis is a universal pitot type speedometer kit and is not limited to a specific engine or boat model; it is intended for boats equipped with or being fitted for a pitot tube speed sensor.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are listed for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat speed range does the Sierra 57899P speedometer cover?\u003c\/strong\u003e The Sierra 57899P reads from 20 to 80 MPH, giving accurate speed tracking across typical recreational boating speeds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of speed sensor does this gauge use?\u003c\/strong\u003e It is a pitot type speedometer, meaning it measures boat speed using a pitot tube that senses water pressure at the hull rather than reading off the engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the 57899P speedometer dial?\u003c\/strong\u003e The dial is 3 inches, matching the standard 3 inch gauge cutout used across Sierra's Amega gauge line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 57899P have a scratch resistant face?\u003c\/strong\u003e Yes, the 57899P uses a domed, scratch resistant lens over the dial face to help maintain visibility and resist wear over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 57899P weigh?\u003c\/strong\u003e The Sierra 57899P weighs 1.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the boxed dimensions of this speedometer kit?\u003c\/strong\u003e The 57899P ships in an 8 x 8 x 8 inch package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 57899P a complete kit or just the gauge head?\u003c\/strong\u003e The 57899P is the full pitot type speedometer kit; a head-only version of the same gauge is sold under a separate part number for buyers who only need to replace the gauge head.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 57899P work with any boat?\u003c\/strong\u003e The 57899P is a universal 3 inch pitot type speedometer intended for boats equipped with, or being fitted for, a pitot tube speed sensor, rather than being tied to one specific engine or boat model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brand makes the 57899P speedometer?\u003c\/strong\u003e The 57899P is manufactured by Sierra as part of its Amega gauge lineup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 57899P come with a warranty?\u003c\/strong\u003e Yes, the Sierra 57899P is covered under Sierra's customer satisfaction warranty, which covers defects in workmanship and materials for the useful life of the product.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 57899P?\u003c\/strong\u003e The UPC for the Sierra 57899P speedometer kit is 731957420244.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988448325851,"sku":"SIE-57899P","price":86.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/57899P.png?v=1784938556","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-57899p-amega-3-inch-pitot-type-speedometer-kit-0-80-mph-scratch-resistant-domed-lens","provider":"Good Vibes Marina","version":"1.0","type":"link"}
