After seeing the new Lowrance scupper transducer mount work so well on Jackson Kayak, a customer of mine decided to figure out a cheap way to do this for other fish finders. In this case we installed a Garmin transducer.
Step 1: Use an 8" piece of electrical grade PVC pipe with threads on one end. Cut the pipe so the threads would just stick up above the deck and the transducer is just tucked into the scupper so it wouldn't drag.
Step 2: Drill a 1/4" hole in the pipe and bolt the transducer to it. The wire runs right through the pipe.
Step 3: Cut a piece of pool noodle to fit around the pipe. This keeps the system snug in the scupper hole.
Step 4: Next install the electrical deck plate to on the top of the scupper. Ours came with a nice foam gasket that helped keep the system quiet and clean.
Thats it! Less than $20 for a super easy clean install for any Jackson Kayak. The expenive part is buying the Jackson. It works great, and its easy to take apart and clean.
We installed an eyebrow fitting to run the wire through and backed it up with some silicone.
So there you have it. Enjoy
