Here is my how to for the Jackson Cuda Scupper Transducer bracket and install.
I used the idea from here. http://www.scoutdoorsblog.com/2012/04/rig-cuda-garmin-150-install-part-1.html

Needed
1 Lowrance X-4 Pro Fish finder with transom mount transducer
1 piece of 1/2″ wide Aluminum stock
1 screw with washer and nut
Hardware that came with X-4
TH Marine Thru Cap for hull pass through deck wiring.

1 Tube of Marine Grade Silicone

Scupper Transducer mount fabrication

Cut aluminum stock for top of bracket (3″ Piece) Center Punch in center and Drill.
Drill Hole in longer piece for transducer mounting.

 

Measure the distance where the transducer hugs the hull inside the scupper to deck.

Add 3/4″ and cut.
Drill hole for angle top mounting between 3″ plate and soon to be angled piece. Then bend the 3/4″ area in a vice.

 

I painted mine to make it look nice.

Pretty easy hope it doesnt come loose.

Then run the wiring thru the deck. Using the TH Marine Thru Cap and marine silicone to seal it. Warning: You dont need to apply much for a full seal. A bead around the top collar is more than enough.

I hope you enjoyed this and are able to follow for the same mounting style! After testing it is far better than the usual inside kayak hull install. I can read accurate water temps and the imaging is much clearer.

Thanks for reading!
