{"product_id":"qbp395781","title":"Garmin Galvanic Isolator Kit, For GT17M-THF Transducer","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Garmin 010-13348-10 is a galvanic isolator kit for the GT17M-THF transducer. It replaces the galvanic isolation parts included with the transducer so the thru-hull installation keeps the intended electrical isolation between the transducer assembly and surrounding metals.\u003c\/p\u003e\u003cp\u003eThe GT17M-THF is a flush-mounted 1 kW midband CHIRP transducer (80-165 kHz). If the isolation parts were damaged during a haul-out, compressed over time, or went missing during service, this kit restores the installation back to the correct stack-up.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eReplacement galvanic isolation parts for GT17M-THF transducer installations\u003c\/li\u003e\n\u003cli\u003eHelps reduce galvanic activity around a thru-hull by keeping dissimilar metals from being directly connected through the mounting stack\u003c\/li\u003e\n\u003cli\u003eUseful for service work when the original isolating hardware is worn, cracked, or missing\u003c\/li\u003e\n\u003cli\u003eApplies to GT17M-THF systems commonly used as 1 kW midband CHIRP (80-165 kHz) flush-mounted thru-hull transducers\u003c\/li\u003e\n\u003cli\u003eTargeted maintenance part that lets you keep the existing transducer in place\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eCompatibility is specific to the GT17M-THF transducer. Confirm the model on your transducer label before ordering, especially if the boat has more than one sonar channel or mixed transducer types.\u003c\/p\u003e\u003cp\u003eThis kit is for the isolation hardware only. It does not change the transducer tilt option, connector style, or cable routing.\u003c\/p\u003e\u003ch6\u003eInstallation and service notes\u003c\/h6\u003e\u003cp\u003eReplace the isolator parts while the boat is out of the water or when the transducer is already being removed for inspection. Take note of the existing hardware order so the isolation components go back in the same positions.\u003c\/p\u003e\u003cp\u003eAfter reassembly, check that the transducer and surrounding underwater metals are not unintentionally bonded together through the mounting hardware. Keeping that separation intact matters most on boats that live in saltwater or spend long stretches connected to shore power.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis kit is a good match for anglers and cruisers running a GT17M-THF thru-hull who want the isolation hardware in the mounting stack kept in working condition over time, particularly on boats stored in marinas with mixed underwater metals.\u003c\/p\u003e\u003cp\u003eIf you are chasing intermittent sonar noise or seeing signs of corrosion around the installation, restoring the isolation parts is a sensible place to start after confirming the rest of the bonding and DC grounds are in good shape.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269600080053,"sku":"QBP395781","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1300695_qbp395781.jpg?v=1771544799","url":"https:\/\/www.qualityboatparts.com\/products\/qbp395781","provider":"Quality Boat Parts","version":"1.0","type":"link"}
