{"product_id":"airmar-st300-shorty-thru-hull","title":"Airmar ST300 Shorty Thru-hull","description":"\u003cp\u003eThe ST300, speed and temperature sensor is low in price and short in size. As part of our Shorty\u003csup\u003e™\u003c\/sup\u003eSeries, it is designed for boats with limited headroom. The total height of housing is only 75 mm (2.96\"). And the P371, low-profile housing is nearly flush and minimizes drag with only 5 mm (3\/16\") extending outside of the hull. The optional, P398, countersunk housing mounts flush, eliminating turbulence for more accurate speed readings.\u003c\/p\u003e\n\u003ch3 class=\"section-title section-title-center\"\u003e\n\u003cb\u003e\u003c\/b\u003e\u003cspan class=\"section-title-main\"\u003eFeatures\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSpeed and fast-response water-temperature sensing\u003c\/li\u003e\n\u003cli\u003eCan be installed in tight spaces with only 153 mm (6\") of headroom\u003c\/li\u003e\n\u003cli\u003eTotal height of housing is only 75 mm (2.96\")\u003c\/li\u003e\n\u003cli\u003eRight-angle cable exit saves space and protects transducer if stepped on\u003c\/li\u003e\n\u003cli\u003eSelf-closing water valve minimizes water entering the boat when the retractable insert is being replaced with the blanking plug\u003c\/li\u003e\n\u003cli\u003eFins on sides of paddlewheel cavity provide improved accuracy in cross-flow conditions\u003c\/li\u003e\n\u003cli\u003ePlastic thru-hull housing is ABYC H-27 compliant\u003c\/li\u003e\n\u003cli\u003eIncluded rubber washer allows tightening of the hull nut to irregular hull surfaces\u003c\/li\u003e\n\u003cli\u003eAvailable in a plastic housing only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eOptions\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpeed sensor only\u003c\/li\u003e\n\u003cli\u003eP398 countersunk housing which requires a special cutter to install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"section-title section-title-center\"\u003e\n\u003cb\u003e\u003c\/b\u003e\u003cspan class=\"section-title-main\"\u003eSpecifications\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCable-Length: 10 m (33')\u003c\/li\u003e\n\u003cli\u003eCommon Use: Cruising\/Racing Sailboats, Leisure\/Yachting, Fishing\u003c\/li\u003e\n\u003cli\u003eFunctions: Speed, Temperature\u003c\/li\u003e\n\u003cli\u003eHole Size: 51 mm (2\")\u003c\/li\u003e\n\u003cli\u003eHousing: Urethane\u003c\/li\u003e\n\u003cli\u003eHull Material: Fiberglass or metal\u003c\/li\u003e\n\u003cli\u003eMounting Style: Low Profile Thru-Hull\u003c\/li\u003e\n\u003cli\u003ePower Rating: N\/A\u003c\/li\u003e\n\u003cli\u003ePulses: 17,000 p\/nm* (4.8 Hz per knot)—*p\/nm = pulses per nautical mile\u003c\/li\u003e\n\u003cli\u003eRetractable housing: Yes\u003c\/li\u003e\n\u003cli\u003eSpeed Range: 0.1 to 40 knots (0.1 to 46 MPH)\u003c\/li\u003e\n\u003cli\u003eTilted Element: No\u003c\/li\u003e\n\u003cli\u003eVoltage: 5 to 25 VDC\u003c\/li\u003e\n\u003cli\u003eWeight: 0.6 kg (1.3 lb.)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Airmar","offers":[{"title":"Default Title","offer_id":51625873178961,"sku":"31-256-2-42","price":122.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4434\/4913\/files\/www.sailrace.com-e7fda4ae1a6219f-lg.png?v=1754727921","url":"https:\/\/www.sailrace.com\/en-caucasus\/products\/airmar-st300-shorty-thru-hull","provider":"SailRACE","version":"1.0","type":"link"}
