Overview
The Garmin 010-12226-00 is a thru-hull mounting hardware kit used with Garmin GT and CV series scanning transducers installed through the hull. It is the small-parts set that secures the transducer stem and supports proper alignment, with three isolation plates included as part of the hardware stack.
This is hardware only for new installs when the transducer calls for this kit, or for replacing missing hardware when a transducer has been removed for service. It does not include a transducer.
Key features
- Mounting hardware kit for Garmin thru-hull scanning transducer installations
- Anti-rotation bolts to help keep the transducer aligned during tightening
- Three isolation plates plus bushings for the thru-hull mounting stack
- Practical replacement set when hardware has been lost, seized, or needs refreshing during a haul-out
Compatibility and fit
This kit is used on Garmin GT and CV series thru-hull scanning transducers and is sold as replacement hardware for GT30-TH and GT30-THP installations. If your transducer parts list calls out 010-12226-00, this is the matching hardware set.
Because thru-hull transducers vary by stem style and housing, confirm the kit is specified for the exact transducer model on your boat. It is not intended for transom-mount brackets.
Installation and setup
Thru-hull installs are typically done during a haul-out. A dry-fit before bedding helps make sure the isolation plates and bushings sit flat and the anti-rotation hardware engages correctly.
Once assembled, check clearance on the inside of the hull so the nut, washers, and cabling are not bearing against stringers, tanks, or sharp edges. A clean run into the bilge makes future servicing less of a headache.
What's included
