INSULATED BILGE LIVEWELL


2


FOREWORD - About Grift co. We know the angler takes fishing with him on and off the water. Fishing isn’t just about catching fish - its the pursuit to master a craft. It’s that perpetual desire to learn and improve. The elaborate preporation the night before, the endless forum scrolling, the satelite reconnaissance; the weather forecast scrutiny. That’s just who we are. There’s a pleasure in using the finest gear when you’re on the water. There’s that same joy in finding succinct and clear information about your hobby. Grift Co. is a new project, aiming to provide passionate anglers with entertaining and educational content. To put it simply, we’ve got cool ideas and we want to share them with you. This livewell project is a prime example! This is our first project we’ve published and we want to know what you think. Feel free to e-mail us at info@grift.co


Introduction: With the 2017 Hobie Australian Bream Series fast approaching, many anglers may be caught out with some new rule changes for this year’s competition. Manual bilge pump livewells are no longer allowed. Under section 11 of the Hobie Rules “Livewells shall have a minimum capacity of 23L with a functioning, battery operated, intake pump.” 1 Previously the rules stated: “Livewells shall have a minimum capacity of 23ltrs with a functioning intake pump.”2 We assume the rules have changed with the intention of keeping the fish fit and healthy for later release. Grift Co entirely supports this decision. For the benefit of our sport and community, improving and managing correctly the wellbeing of fish is key to sustained support of our tournaments. Although this rule may lead some to purchasing a genuine Hobie Livewell, the keen DIYers find this as a great opportunity for some justified tinkering. This document should provide enough information for you to build your own battery operated bilge, ready for the upcoming Hobie Series. 2017 Hobie Kayak Bream Series Rules - Hobie Fishing www.hobiefishing.com.au/bream/bream-rules 2016 Hobie Kayak Bream Series Rules - Hobie Fishing 2 1


WHAT’S IT GONNA COST?: The aim of this project is to be cheaper than a Hobie XL Livewell. A Hobie XL Livewell lightens the wallet by ~ $650. The smaller Hobie Livewell ~$450. Granted, you could probably pick a second hand one up cheaper - but we’re here to have fun building something. The rough cost to build this livewell design is $470.


THE TOOLS: You’re not gonna make it very far without a few tools. In an effort to keep this as accessible as possible, we have used common tools rather than specialised tools. Cordless Drill Drill Set 25mm Spade Bit/ Hole Saw Snap Blade Knife (Stanley Knife) Hack Saw Vice Grips Lighter Ruler Utility Scissors Soldering Iron Solder Optional: Cable Strippers Crimper


The Bits and pieces: To reduce the guess work of what pieces you’ll need and where to go, we’ve put together a table of all the parts required divided into their respective stores. There’s absolutely no reason why you can’t go elsewhere, and if you find something cheaper elsewhere, please let me know and I will update this document!

The PLUMBING:


Step 1 Using a saw, cut the flange off of the end of both skin fittings We’re only using the 1” threaded rod section of the fitting as we’ll be attaching threaded pieces to the interior and exterior

Step 2 Attach the 1” Hose Fitting to an end of the threaded rod.

Step 3 Using your third hose fitting, align it to fit snug against the exterior corner details. We will use this as a guide to find the centre of the main hole.

11


Step 4 Using the largest drill bit that fits into the hose fitting - begin drilling into the sidewall of the esky.

Step 5 It is not necessary to penetrate through the entirity of the sidewall. This mark is the centre of our main hole. Alternatively - you can use a pencil/ pen to mark the centre.

Step 6 Create a pilot hole going through both exterior and interior skin.

12


Step 7 Using a 25mm Spade Bit, we can create a tight hole that the threaded can screwed into, creating a tight seal prior to silicone.

Step 8 With the spade bit, drill through both walls of the esky using the spot drilled hole.

Step 9 Start winding in the threaded rod with hose fitting on the outside. Stop before winding the whole way in. Leave ~10mm to apply silicone

13


Step 10 Apply a liberal amount of silicone around the exposed thread.

Step 11 Continue tightening till hose fitting has seated in final position. Using a wet finger, clean up excess silicone.

Step 12 Apply silicone to thread on inside of esky.

14


Step 13 Screw on interior ‘nut’ tight. Nut is originally supplied with the skin fittings.

Step 14 Attach Flowrite airation nozzle to remaining exposed thread.

Step 15 Repeat steps 3-13 on the opposite side for outlet hose

15


Step 16 Cut remaining exposed thread from outlet

Step 17 Attach female hose fitting to end of 20mm hose.

Step 18 Plug hose into male inlet fitting.

16


Step 19 Attach Hose fittings to bilge pump

Step 20 Position Bilge pump at level you want. This will provide an inidication of how long to cut the hose. Note: For this project, we have used a ram arm to fix the bilge solidly to the side of the boat. This is not necessary and you can easily just have the bilge hose hanging in the water freely.

Step 21 Cut hose to length.

17


Step 22 Repeat steps 18, 20 and 21 for outlet hose.

Step 23 Attach Inlet hose to bilge and test for leaks.

TAKE A BREAK! You’re halfway there
