It reads engine speed across a 0-3500 RPM range and is designed to work with magnetic pickup senders in the 90-180 teeth range, matching the tooth count of the diesel flywheel or drive plate it is paired with. As a magnetic pickup tachometer, the 82303P reads engine RPM directly from the pulses generated by the pickup sender rather than from an alternator or points signal, which makes it suited to diesel powerplants that do not generate a standard tach signal on their own.\u003c\/p\u003e\u003cp\u003eThe gauge is built into a 3 inch housing sized to match standard helm gauge cutouts, so it drops into existing diesel-tach openings without modification. It is intended for use on diesel-powered boats where the helm calls for direct, panel-mounted RPM readout paired with a compatible magnetic pickup sender.\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 82303P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Diesel Magnetic Pickup Tachometer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Diameter:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM Range:\u003c\/strong\u003e 0-3500 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSender Compatibility:\u003c\/strong\u003e 90-180 teeth magnetic pickup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSender Requirement:\u003c\/strong\u003e Requires \"B\" designation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Nylon housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Package Dimensions:\u003c\/strong\u003e 4.5 inches L x 6.0 inches W x 8.0 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 731957351364\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDiesel engines equipped with a magnetic pickup sender in the 90-180 teeth range and a \"B\" designation sender configuration.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are specified for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Sierra 82303P tachometer designed for?\u003c\/strong\u003e The Sierra 82303P is designed for diesel engines that use a magnetic pickup sender, reading engine speed from 0 to 3500 RPM.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the 82303P gauge?\u003c\/strong\u003e It is a 3 inch diameter gauge, sized to fit standard 3 inch helm gauge cutouts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat RPM range does the 82303P tachometer read?\u003c\/strong\u003e The gauge reads from 0 to 3500 RPM, part number 82303P.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat sender is compatible with the 82303P?\u003c\/strong\u003e The 82303P is compatible with a magnetic pickup sender in the 90 to 180 teeth range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 82303P require a specific sender configuration?\u003c\/strong\u003e Yes, the Sierra 82303P requires a \"B\" designation sender configuration to operate correctly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 82303P an electric or mechanical tachometer?\u003c\/strong\u003e It is an electric tachometer, driven by pulses from a magnetic pickup sender rather than a mechanical cable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 82303P housing made of?\u003c\/strong\u003e The 82303P tachometer has a nylon housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 82303P weigh?\u003c\/strong\u003e The 82303P weighs 0.7 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the 82303P tachometer?\u003c\/strong\u003e The item ships in a package measuring 4.5 inches long by 6.0 inches wide by 8.0 inches high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the Sierra 82303P made?\u003c\/strong\u003e The 82303P tachometer's country of origin is the United States.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 82303P be used with a gas outboard engine?\u003c\/strong\u003e No, the 82303P is built for diesel engines using a magnetic pickup sender in the 90-180 teeth range; it is not the gas outboard tachometer variant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does \"magnetic pickup\" mean for this tachometer?\u003c\/strong\u003e It means the 82303P reads engine RPM from pulses generated by a magnetic pickup sender mounted near the flywheel or drive plate teeth, rather than from an alternator signal.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988454322395,"sku":"SIE-82303P","price":92.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/82303P__44916.1739462469.500.750.jpg?v=1785187978","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-82303p-heavy-duty-diesel-tachometer-3-inch-magnetic-pickup-12v-electric-marine-gauge","provider":"Good Vibes Marina","version":"1.0","type":"link"}
