I realize that I’m not the first kayak angler to change electronics brands and encounter installation issues. But I figured that the more information and tips available online, the less complicated the task might be for others. Let me start at the beginning.

I like to change the electronics on my kayaks and boats every three to five years. Because I write about electronics for our publications, I usually swap electronics brands each time so that I can become more familiar with the user interfaces.

When I bought my Hobie Compass kayak several years ago, we installed a Lowrance display and transducer, using Hobie’s Lowrance-Ready transducer mounting system — which positions the long slender transom-mount sensor into a pocket beneath the hull. The transducer fastens to the hull using a plastic adapter plate and screws. Easy-peasy.

After three years, I decided to install a Garmin EchoMap UHD 74sv. However, the holes on the Garmin transducer did not match up with the holes on the adapter plate. My own internet search began. I found the BerleyPro Hobie Transducer Mount.

My initial excitement waned as I noticed the company was located in Australia. Shipping would be possible, but costly. Another search located the same product at fishingonline.com. At $73.14 with free shipping, I hit buy.

Once I found this product, the rest of the install went fairly easily, although I managed to fasten on the new adapter plate upside down at first. Attaching the Garmin’s power cord to a Nocqua cable to plug into my Li-ion battery was a simple matter of matching red wires and black wires.

I feel great satisfaction when I plug in something and it works instantly. I used Garmin’s Active Captain app to download and install g3 Vision charts to my MFD. My first fishing trip with the new Garmin showed me all kinds of new functionality as well as pointing out fish and bait schools.

Here’s the short video capture of the process:
