Lowrance has introduced to the kayak fishing community what should be considered the ultimate transducer mounting system for sit-on-top fishing kayaks. With the “Transducer Kayak Scupper Mount” the transducer is totally submerged in the water. This guarantees maximum sonar signal return sensitivity, producing the absolute clearest underwater returns of structure and fish possible.

According to Lowrance, this transducer mounting system works with any Lowrance HDS, Elite, Elite DSI, Mark, Mark DSI and X-Series fishfinders. It fits all Lowrance 200 kHz and Downscan ImagingTM  Skimmer® transducers.

The mounting system is compatible with the following scupper dimensions:
•    Circumference: 1” to 1.5” (2.4 to 3.8 cm)
•    Depth: 1.5” – 9.25”(4 – 23.5 cm)

My problem with this mounting system was using the scupper holes of the Jackson Cuda. The depth of the holes was not the problem, but the shape was. The scuppers of the Cuda are approximately 1.25” X 2”,which does not fit the compatibility descriptions . The deep channels on the bottom of the Cuda would also allow the transducer to be mounted below the curvature of the Cuda hull, providing protection for the unit.

So, I had to figure out a solution, which is actually pretty simple for any Cuda. My answer was to obtain a 2” flat washer with a 1” opening, and about 2” of a  pool noodle (~2.38” diameter). Add the washer to the bottom plastic part that sits on the top of the assembly. The purpose of the washer is to re-enforce this part when tightening the mounting system together. Without the washer this plastic part will just bend. Then the finished cover will not clip to this part.

Now take the 2” piece of the noodle, and carve the approximate shape of the scupper hole. This will be added to the assembly just above the foam circle. Run the transducer wires through the pool noodle.

Now all you have to do with these additional parts in place is to follow the very simple instructions that Lowrance provides with this product.
