It displays a dial range of 120 to 240 degrees F, giving boaters a clear read on whether the engine is running within a safe operating range or trending toward overheating. The gauge face is scratch resistant, helping it stay legible in the helm environment where sun exposure, spray, and routine handling can degrade lesser gauges over time.\u003c\/p\u003e\u003cp\u003eConstruction combines alloy steel, brass, and stainless steel components, materials chosen for corrosion resistance in the marine environment. The 65509P is built to Sierra's standard for engine and drive parts, meeting or exceeding the specification of the original equipment gauge it replaces. It pairs with a sender using code D for proper calibration, so buyers should confirm their sender matches before installation. As a helm instrument, it mounts into a standard 2 inch gauge panel cutout alongside other Sierra Lido series gauges for a matched instrument cluster 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 65509P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Temperature Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Lido\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Size:\u003c\/strong\u003e 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Range:\u003c\/strong\u003e 120 to 240 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSender Code:\u003c\/strong\u003e D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Application:\u003c\/strong\u003e I\/O, I\/B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy Steel, Brass, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 5.1 x 3.9 x 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 731957423382\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFor I\/O (inboard\/outboard) and I\/B (inboard) engines using a sender code D.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the dial range on the Sierra 65509P gauge?\u003c\/strong\u003e The dial range on the Sierra 65509P water temperature gauge is 120 to 240 degrees F, covering the normal operating band for marine engine coolant temperature.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is this gauge?\u003c\/strong\u003e The Sierra 65509P has a 2 inch dial, sized to fit a standard 2 inch helm gauge cutout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the 65509P compatible with?\u003c\/strong\u003e This gauge is designed for I\/O (inboard\/outboard) and I\/B (inboard) engine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 65509P gauge need a specific sender?\u003c\/strong\u003e Yes, the Sierra 65509P is calibrated to work with a sender using code D; using a different sender code will give an inaccurate reading.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the gauge face made of?\u003c\/strong\u003e The 65509P dial face is scratch resistant, and the gauge assembly is constructed of alloy steel, brass, and stainless steel components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this gauge match other gauges in a Sierra Lido panel?\u003c\/strong\u003e Yes, the 65509P is part of Sierra's Lido series of gauges, designed to match in style and dial size with other Lido instruments for a uniform helm panel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 65509P weigh?\u003c\/strong\u003e The Sierra 65509P weighs 0.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the physical dimensions of the gauge?\u003c\/strong\u003e The 65509P measures 5.1 x 3.9 x 0.8 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 65509P an OEM replacement or an upgrade over the original gauge?\u003c\/strong\u003e The 65509P is built to meet or exceed the specification of the original equipment water temperature gauge it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 65509P?\u003c\/strong\u003e The order includes one Sierra 65509P Lido water temperature gauge; the required sender (code D) is a separate component.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988450488539,"sku":"SIE-65509P","price":47.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/65509P.png?v=1784938645","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-65509p-lido-water-temperature-gauge-2-inch-120-to-240-degrees-f-scratch-resistant-dial-for-inboard-and-sterndrive-boats","provider":"Good Vibes Marina","version":"1.0","type":"link"}
