{"product_id":"qbp114252","title":"Raymarine Fairing Block, For B744V and B744VL Transducers","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Raymarine E66023 is a high-performance fairing block for Raymarine B744V and B744VL thru-hull transducers. It helps the transducer sit at the correct angle on the hull so the sonar face can run cleaner through the water, which matters most when the boat is underway and water flow around the fitting becomes less forgiving.\u003c\/p\u003e\u003cp\u003eThis block is made from urethane and measures approximately 3 inches high by 3 inches wide by 13.73 inches long. It is a fit-focused transducer mounting accessory, not a transducer by itself, so the B744V or B744VL thru-hull transducer is required separately.\u003c\/p\u003e\u003cp\u003eUse it when a thru-hull installation needs a fairer shape outside the hull rather than a simple flush mounting approach. On fishing boats, cruisers, and other vessels that rely on steady depth, speed, and temperature readings from a B744-series triducer, the fairing block helps reduce disturbed water at the sensor face.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eMatches Raymarine B744V and B744VL thru-hull transducers for compatible installations.\u003c\/li\u003e\n\u003cli\u003eUrethane construction suits the underwater mounting role and can be shaped for hull fit during installation.\u003c\/li\u003e\n\u003cli\u003eFairing profile helps reduce turbulence around the transducer face when the vessel is moving.\u003c\/li\u003e\n\u003cli\u003eSupports correct angular positioning of the transducer on the hull for cleaner sonar readings underway.\u003c\/li\u003e\n\u003cli\u003eApproximate product dimensions are 3 inches high by 3 inches wide by 13.73 inches long.\u003c\/li\u003e\n\u003cli\u003eUseful for installations where a thru-hull triducer needs fair water flow rather than sitting directly against a sloped hull surface.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eBefore cutting or bedding anything, confirm the installed transducer is a Raymarine B744V or B744VL model and check the hull location for clean water flow. The fairing block is normally fitted on the outside of the hull and trimmed or oriented so the transducer face sits correctly relative to the waterline.\u003c\/p\u003e\u003cp\u003eBecause this part is installed below the waterline, surface preparation, bedding compound selection, and final tightening should follow normal thru-hull installation practice for the vessel material. The block should sit evenly against the hull, with no rocking or gaps that could affect sealing or water flow.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis is a practical replacement or installation part for boats using a B744-series thru-hull triducer where readings need to stay stable while running. It is especially relevant for owners who use their sonar for depth awareness, fishfinding, and temperature or speed data while cruising, fishing, or navigating in changing bottom conditions.\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":52023857742005,"sku":"QBP114252","price":99.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1330886_qbp114252.webp?v=1780192050","url":"https:\/\/www.qualityboatparts.com\/products\/qbp114252","provider":"Quality Boat Parts","version":"1.0","type":"link"}
