If the propeller is missing, chipped, or not spinning freely, wind speed can drop to zero, lag behind gusts, or read inconsistently. Replacing the propeller restores the rotating element so the transducer can read wind speed normally again.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eReplacement propeller for Garmin gWind wind transducer setups, including those paired with GND 10.\u003c\/li\u003e\n\u003cli\u003e3-bladed rotor used for wind-speed sensing on the gWind twin-fin style transducer.\u003c\/li\u003e\n\u003cli\u003eAddresses common issues after loss, impact, or binding that can cause wind-speed dropouts or erratic readings.\u003c\/li\u003e\n\u003cli\u003ePractical spare to keep aboard for boats that depend on masthead wind data for instruments and sailing displays.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis is a wind transducer propeller, not a propulsion propeller for an engine or trolling motor. It is intended for Garmin gWind wind transducer hardware found at the masthead. Confirm your boat has a gWind transducer before ordering.\u003c\/p\u003e\u003cp\u003eIf your installation includes a Garmin GND 10, this propeller still fits the masthead gWind sensor, since the GND 10 is the interface and the rotating element remains on the transducer itself.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eReplacement is typically done at the masthead. Before fitting the new propeller, rinse and wipe the shaft and hub area so salt crystals and grit do not bind the rotor. After installation, spin the propeller by hand to confirm it turns freely and does not rub on the fins.\u003c\/p\u003e\u003cp\u003eOnce back under way, check that wind speed responds smoothly in light air and ramps up cleanly in gusts. If readings are still inconsistent, inspect the transducer for shaft play or fin damage from the same event that took out the propeller.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis replacement is a good match for cruising and racing sailboats that rely on masthead wind speed for instrument displays, wind-based sailing decisions, and autopilot wind modes.\u003c\/p\u003e\u003cp\u003eIt also makes sense as a small spare for offshore passages or regattas, where a missing propeller can take wind speed offline at the worst time.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269236519093,"sku":"QBP540578","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298981_qbp540578.jpg?v=1771542690","url":"https:\/\/www.qualityboatparts.com\/products\/qbp540578","provider":"Quality Boat Parts","version":"1.0","type":"link"}
