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!

Installing electronics on a kayak can bring on many challenges. One of the major challenges are how to wire through the kayaks bulkhead and what products are manufactured to cap large drilled holes post wiring the fish finder. This article covers common Types of Hull Pass-Throughs.

After a lot of research here are a few types of hull pass-through caps for wiring electronics on your kayak.

Rubber Stopper 1/4″ – 1.5″ Drill

rubber stoppersCommonly used for drain plugs and scupper holes the Rubber stopper can also be used for Thru Hull Wiring. Simply with a sharp box cutter cut a slit from the outer diameter to the center hole. This will allow you to pass the wire into the center of the stopper. Runt he connecting plug through the hole and simply press the stopper in small diameter of the flange first to make a seal. This method works but is not recommended for a permanent install. The stopper over time can come loose so check it every now and then. It wouldn’t hurt to silicone them in.

Cable Gland 1/4″ – 1″ Drill

The cable gland is a wiring connector that is able to match wire diameters with a grommet that seals tightening down a lock nut.

On the bottom of the gland is a threaded portion that is able to pass through a drilled hole in the hull and tightened down with an included ring nut. Cable glands do work great but the only problem i see with them is the protrusion they create. They are easily snagged by fishing line. In areas that fishing line will not snag they are great.

Cable Clam pass through 1″ – 2″ Drill

Cable clams are a good solution but protrude the most. They require 4 large screws holes perfectly aligned. Personally I think they are the most unsightly for applying on a kayak. They are purposed more for boats. They are also the most expensive and hardest to install.

TH Marine CeaCap 3/4″ Drill

CeaCap (Large)The CeaCap is the most flush option but will only work with cable plugs that will pass through a 3/4″ hole. It is threaded and will turn the wire 90 degrees so it is flush with the hull. IT will allow for two 12 gauge wires to pass through.

West Marine Wire Cap 1″  Drill

 

hullpassproducts (Large)The best out of them all I have found for large connectors is the West Marine Wire Cap. Fish finder connectors with 1″ diameter will work with this cap to cover the required hole to pass through the wire for both the transducer and the power. You may run two wires at 14 gauge through this cap max and 1 wire at 8 gauge id say max.
