On the surface, if anyone can point me to a model that fits that need, I'd be eternally grateful.

On a deeper level, I'm wondering if it's just me, or is it insanely difficult to find information about this stuff? Looking at the advertisements, they say nothing about mounting dimensions or even the data technology in use. Especially with the data technology, it's frequently some proprietary protocol that may or may not be NMEA 2000 compatible.

Maybe I'm just impatient or really bad at research ... but it feels like I spend an inordinate amount of time trying to find out important bits of information about the equipment I'm considering buying. Is it just me?

If you don't want to replace the thru-hull fitting then you'll really need to know what is on the label/tag at the transducer end of the cable in terms of model/part #.

With this data you can then go through any legitimate marine electronics dealer/installer who has a Gemeco account, and order the correct transducer to fit in that thru-hull.

The current Gemeco catalog is 671 pages long so without the correct part numbers you're shooting at darts blind folded. Gemeco is the wholesale/distribution arm of Airmar.
