It connects via an 8-pin plug and outputs standard dual-frequency sonar at 77\/200 kHz with 500 W power, with depth readings rated up to 900 ft and a built-in water temperature sensor.\u003c\/p\u003e\u003cp\u003eThe housing sits nearly flush, with about 5 mm of the body outside the hull to keep drag down. It uses a right-angle cable exit to save headroom inside the bilge area and reduce the chance of the cable getting stepped on, and the attached cable is 30 ft long.\u003c\/p\u003e\u003cp\u003eThis transducer is a solid match for fiberglass and wood hulls where you want a permanent, clean thru-hull install for cruising, fishing, and everyday navigation depth tracking. Bronze thru-hulls are not a fit for metal hulls due to corrosion risk.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eStandard dual-frequency sonar: 77\/200 kHz, 500 W, rated for depths up to 900 ft\u003c\/li\u003e\n\u003cli\u003eDepth and water temperature output (no speed sensor)\u003c\/li\u003e\n\u003cli\u003e8-pin transducer connector for Garmin sonar ports that accept 8-pin plugs\u003c\/li\u003e\n\u003cli\u003eTilted element options that match common deadrise ranges, helping keep the beam pointed toward the bottom\u003c\/li\u003e\n\u003cli\u003eLow-profile bronze thru-hull body with about 5 mm outside-hull protrusion to reduce drag\u003c\/li\u003e\n\u003cli\u003eRight-angle cable exit for low headroom installations and better protection in busy bilge spaces\u003c\/li\u003e\n\u003cli\u003e30 ft cable length for routing to the helm or electronics box without splices in many installs\u003c\/li\u003e\n\u003cli\u003eABYC H-27 compliant housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in two tilt configurations. The tilt angle is selected to match the hull deadrise at the mounting location, so the sonar beam runs closer to vertical once the transducer is installed.\u003c\/p\u003e\u003cp\u003eBoth versions share the same bronze thru-hull format, 8-pin connection, 30 ft cable, and depth plus water temperature sensing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e010-10217-22: Tilt 20° (for 16° to 24° hull deadrise). This tilt is intended for steeper deadrise sections where a straight, non-tilted element would aim the beam off-angle.\u003c\/li\u003e\n\u003cli\u003e010-10217-21: Tilt 12° (for 8° to 15° hull deadrise). This tilt fits moderate deadrise hulls and helps keep bottom tracking stable as speed increases.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eBecause the tilt is built into the element, the key fit check is the deadrise where you plan to drill, not the overall hull shape. Measure deadrise at the install spot with an angle finder or digital level, then match it to the 12° or 20° option.\u003c\/p\u003e\u003cp\u003eBronze thru-hull housings are commonly used on fiberglass and wood hulls. They should not be installed in metal hulls due to electrolytic corrosion risk.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThis is a below-the-waterline thru-hull install that typically uses a 2 in (51 mm) hole through the hull. Plan the location so the transducer face stays in clean water flow and remains continuously submerged, away from intakes, strakes, steps, and other turbulence sources.\u003c\/p\u003e\u003cp\u003eDuring installation, align the arrow on top of the housing toward the keel or centerline so the tilt works as intended. A rubber washer is supplied to help the hull nut seat properly on hull surfaces that are not perfectly flat, and proper marine sealant is required to bed and seal the fitting. After launch, check for leaks promptly.\u003c\/p\u003e\u003ch6\u003eSonar and system integration\u003c\/h6\u003e\u003cp\u003eThe B619 uses an 8-pin connector and is intended for Garmin sonar devices that accept an 8-pin transducer plug. If your sounder uses a different transducer port style, an adapter cable may be required.\u003c\/p\u003e\u003cp\u003eThis is standard dual-frequency sonar rather than CHIRP or scanning imaging, so it pairs best with setups that need dependable depth and temperature on a permanent thru-hull mount.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eKeep the face clean for reliable readings, especially in warm or high-growth water. If you apply antifouling, use a water-based coating that is safe for transducers and avoid harsh solvents on the acoustic window and seals.\u003c\/p\u003e\u003cp\u003ePeriodically inspect the cable routing, strain relief, and the inside-hull nut area for any signs of movement or seepage, especially after the first few trips and after heavy pounding.\u003c\/p\u003e\u003ch6\u003eSafety notice\u003c\/h6\u003e\u003cp\u003eWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
