Tuna Tube Installation

Kodiak Marine Tuna Tubes

Thank you for purchasing a Kodiak Tuna Tube™. The Kodiak Marine K-1500 bait pump is recommended to run two tubes. The Kodiak K-700 is recommended for one tube. If you are running two tubes, a manifold can be made utilizing PVC fittings and ball valves. Run 1” hose from your Kodiak K-1500 into a 1” PVC(T), then reduce the two outlets to ¾” and attach valves to both hose runs. If you are running ,ore than one tube per pump, you’ll need to install a flow control valve so that you can shut down one tube if it is not in use. You may choose to run a 110V (if available) pump (such as a small swimming pool pump to provide water for your Tuna Tubes™, as an alternative to your bait pumps.

Water Flow

When the pump is turned on, water should begin to overflow the tube in approximately 20 to 30 seconds. This is the fill time. Catch a bait and put it headfirst into the tube that is running. When you catch a second bait, open the valve, let the second tube fill and insert bait #2.

Helpful Hints

Kodiak also manufactures thru-hull and transom mount bait pumps. The general rule for water flow is to provide a turnover of water in 20 to 30 seconds. This water flow will keep sufficient water flowing over the gills of your baits to provide enough oxygen to keep them alive. After installation, the user should check the tubes, with the pump running, to make sure there are no air bubbles being introduced into the water flow by the pump, loose clamps, etc. Air bubbles are detrimental to the health of your baits.

Baits should be hooked and boated in the quickest manner possible. Use heavy line, large hook and a tight drag. Net fish if they cannot be flipped aboard – do not use gaffs. Insert baits into your Tuna Tubes0153 head first. If the tail of the bait is sticking out of the tube, drape it with a wet towel to prevent drying. Smaller baits, say 3 to 7 pounds, may be suspended in the tube by using large rubber bands. Loop the rubber bands around the fork of the tail and around the outside of the tube. If baits are small enough, two may be stacked, headfirst, side by side in a tube.

Good Fishing!
