The Jackson Big Rig FD/HD is a unique install as its transducer ready scupper is located in the center of the deck between the hull and the pod. At Delaware Paddlesports we used thru hullHobie Thru Hull 3 Way Plug Kit“> Hobie Thru Hull 3 Way Plug Kit. Drilling through the deck is not always the best option but in this case the only option. These unique fittings are gasketed waterproof and are the cleanest way to install on the Big Rig HD FD.

Utilizing the Lowrance 000-10606-001 Kayak Scupper Mount for Skimmer Type Transducers you can avoid many issues with a cap and bungee system. This scupper mounting system can accept many other brand transducers also. Although it is set for older model transducers it can be modified to work with the latest skmmer transducers from Lowrance.

Also for the Lowrance display head unit I used a Hobie Thru Hull 3 Way Plug Kit. Water tight and clean!

Lowrance Elite 5 TI TotalScan Kayak Install for Jackson Kayak Big Rig

Luckily the Jackson Kayak Big Rig has factory molded scuppers that accept large transducers like the Raymarine Dragonfly. Although the Lowrance Elite 5 TI TotalScan transducer is over 10″ long it mounts in pretty flush on the Jackson Kayak Big Rig with some modifications.

TotalScan Kayak Scupper Transducer Install & Mods:

I had to flip the mounting bracket upside down then mount the transducer to bracket. This allowed an extra 1/4″ of space so the transducer mounted closer to the hull and more flush inside the scupper trough.

Transducer mounting bracket cable notch modification. (Optional)

I opted to notch out the mounting bracket to receive the transducer cable flush. Doing this allowed me to install the transducer with the wire forward. I figured the less exposed cable the more protected it would be to objects in the water damaging it. Simply I marked with a sharpie marker the center and width of the cable. Using a vise and an angle grinder to notch in a space for the cable to pass through.

Using the Lowrance Kayak Scupper Mounting Kit. With a simple modification using a bolt and about 6 washers you can pack out the middle of the bracket to sit flush on the transom bracket. See the image below.

A Big Rig application.

To secure the transducer so it will not move at all add bungee to hold cantilevered end taught to the hull.The bungee will pass through the scupper behind the actual mounting plate. Using a scrap piece of plastic drill with a hole saw to create a tie down plug. Then pass through the bungee and tie a knot this will hold the transducer taught in the scupper. I ran the new transducer wire through the same thru hull holes as the HDI skimmer location.

Jackson Kayak has really simplified the installation of fish finders for the end user first with the Big Rig and now with its new offshore kayak the Kraken! Like the Big Rig the Kraken is Raymarine Dragonfly ready. This means the Lowrance HDI skimmer also fits really nice in this scupper with the Lowrance Scupper Mount Kit! This article covers how to install a Lowrance skimmer transducer & Fish Finder on the Kraken in a scupper hole so the transducer is in the water.

Things you will need:

• Lowrance HDI Skimmer
• Lowrance Scupper Transducer Mount Kit
• (2) West Marine Wire Cap
• Drill with 1″ hole saw
• Philips head screw driver
• 2 waterproof butt connectors
• 3/8″ diameter x 4″ long heat shrink tubing

Install:

First unwrap the transducer cable from its packaging and twist tie. run the wire from the hull through the scupper up to the deck . Unboxing the scupper mount simply follow the diagram. With the HDI/Chirp skimmer you will simply slide the transducer on the track at the bottom of the transducer mount. It needs to be positioned forward on the mount so slide the track all the way up to where the wire goes inside the transducer. Now Slide the foam insert and then through the top bracket that will fit perfectly to the scupper. Using the wing nut thread it all the way down to the top bracket to snug it up. Once snug you may now clip the threaded plastic off flush with the bracket and clip the cap over.

Now to run the transducer wire to the inside of the kayak.  Using a 1″ diameter hole saw drill through the radius area of the hatch. BE careful as the plastic is ver thin here. Once the hole is made runt he cable through the wire cap and screw the wire cap in using the screw driver. The screws will self tap.

Next for wiring back to the fish finder unit and battery. This is really up to you where you would like the location to be. I tend to keep it out of the way of where fishing line cannot fowl with the wires and also so adjusting the location of the fish finder on the fly. Also take into consideration the factory installed battery box tray between the front day hatch and the center hatch (7). In my case the fish finder location is to be on the center hatch tracks and being fully adjustable to slide the entire length of the track. The decision to run the wired through the deck in front of the center hatch in my case was the conclusion. This location allows the wires to swing and not get int he way when operating the hatch. The next step will be fabricating a track mount console that will allow me to mount the fish finder to the center of the hatch.

To connect the battery using a plug connector first slide a 3-4″ x 3/8″ diameter heat shrink tubing over the bare wire side of the Lowrance power wire. Crimp the butt connectors to the wires with the  correct polarity and heat shrink the connectors. Then slide over the 3/8″ heat shrink tubing and shrink  the connectors in. I prefer to use clear heat shrink tubing due to all of the use int he salt water. Sometimes connections fail and have water seep in. This speeds up the trouble shooting as now the corrosion is detectable visually.
