It is a depth-only sensor with a thru-hull mounting style, supplied with 6 meters of cable for routing back to the instrument system.\u003c\/p\u003e\u003cp\u003eThis transducer uses a 2\" (51 mm) diameter fitting and supports hull thicknesses up to 2.125\" (55 mm), making those two measurements the key checks before ordering. The retractable body can be removed for cleaning, which is useful on boats that sit in the water and collect growth around the hull fitting.\u003c\/p\u003e\u003cp\u003eThe T912 has been used as the standard depth transducer with mn100 T100 Speed and Depth systems since August 2004. Earlier T100 installations may have been supplied with the T905 Shorty Depth Transducer, so checking the existing transducer style and hull fitting is important before replacement.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eRetractable thru-hull depth transducer for Raymarine mn100 T100 Speed and Depth systems\u003c\/li\u003e\n\u003cli\u003eDepth-only configuration with no speed or temperature function\u003c\/li\u003e\n\u003cli\u003e2\" (51 mm) diameter fitting for matching the existing hull opening\u003c\/li\u003e\n\u003cli\u003eWorks with hull thicknesses up to 2.125\" (55 mm)\u003c\/li\u003e\n\u003cli\u003eRemovable insert helps with cleaning and service when marine growth builds up\u003c\/li\u003e\n\u003cli\u003eSupplied with 6 meters of cable for installation routing\u003c\/li\u003e\n\u003cli\u003eReplacement path for T100 systems supplied from August 2004 onward\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eBefore installation, confirm the existing hull opening, hull thickness, and cable route. The 2\" (51 mm) diameter and 2.125\" (55 mm) maximum hull thickness are the main fit points, especially when replacing an older unit rather than installing into a new hull.\u003c\/p\u003e\u003cp\u003eBecause this is a thru-hull transducer, installation should place the sensing face in clean water flow and away from turbulence caused by strakes, keels, through-hull fittings, or prop wash. The retractable format is helpful for routine cleaning, but the hull fitting still needs correct bedding and inspection as part of normal below-waterline maintenance.\u003c\/p\u003e\u003ch6\u003eCompatibility and use on board\u003c\/h6\u003e\u003cp\u003eThe T912 is intended for Raymarine mn100 T100 Speed and Depth systems where a separate depth transducer is required. It does not add speed, temperature, or CHIRP sonar functions, so it is best matched to installations that only need depth input through the compatible instrument system.\u003c\/p\u003e\u003cp\u003eThis is a practical replacement part for sailors and powerboat owners maintaining an existing Raymarine wireless instrument setup, especially where the original depth reading is still part of the cockpit navigation picture for coastal cruising, club racing, or general depth awareness in shallow water.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eRaymarine T912 retractable thru-hull depth transducer\u003c\/li\u003e\n\u003cli\u003e6 m cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":52024105140405,"sku":"QBP918903","price":189.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1330498_qbp918903.jpg?v=1780192108","url":"https:\/\/www.qualityboatparts.com\/products\/qbp918903","provider":"Quality Boat Parts","version":"1.0","type":"link"}
