Lowrance Scupper Mount Install

After a few months of using a swing arm mount on my Lowrance Elite 5 HDI, I wanted to try something different. Ocean Kayak provides a pretty deep scupper hole designed for a transducer on the Prowler Big Game II. The question is how does one go about mounting the transducer to that hole? The answer lies in with Lowrance’s kit specifically designed for mounting one of their transducer into a Kayak’s scupper. The kit is simple, but ingenious. There are very few components and just a few steps.

The first thing that you need to do is to mount the bracket and threaded rod on your transducer. There are several options to do this, but for my application on the Elite 5 transducer, the best option is to leave the cap off the top of the transducer and line up the slots on the provided bracket to the grooves on the transducer.

Once the bracket is connected to the transducer, you can slide the threaded plastic rod, which is now connected to the transducer, from the bottom of the kayak up to the top. Hold onto the rod so that the transducer doesn’t fall, slide the mounting cap over the rod and begin threading the provided wing nut onto the rod. The rod is extremely long at this point and it will take a while to thread the nut down to the top bracket.

After snugging down the wing nut and positioning everything correctly, you can cut the rod down. This completes the majority of the install. All that is left is to place the Lowrance branded cap over the top bracket and run your wiring to your liking.

Please see my YouTube video for a step-by-step install of this kit on an Ocean Kayak Prowler Big Game II with Lowrance Elite 5 HDI.

Greg is an active duty Army Officer and AH-64D Apache Pilot. He started kayak fishing in the summer of 2011 with his father at his home away from home in Destin, Florida as a cheap way to get on the bay and out into the gulf of mexico. Greg loved kayak fishing so much that he soon forgot about buying a boat and has since owned four kayaks. Whenever he is not out fishing at his current duty station you can catch him working on his cars, shooting guns or enjoying the outdoors with his wife and two dogs.

This is not working on my Ocean Kayak BG Prowler 2. The transducer sticks out too much and is not protected within the recessed hull. I have the Lowrance Elite 4X Chirp.

Help me with a solution please.

Plain and simple, the hole that ocean kayak provides is not big enough to fit the larger transducers on the market like your chirp transducer. You can always use the swing arm option if you don't want to use the scupper.

I have the original Ok Prowler 15. Can you set the transducer up to shoot thru the hull? or will that interfere with its performance? Looking at the Elite 5/GPS model. Thanks

Supposedly, down scan will not be as good if you install the transducer to shoot through the hull. I have only installed 2D sonar to shoot through the hull and it worked just fine, but I have zero experience with DSI through the hull. Might be worth a try, but just know that your DSI might not work at its best.
