Hobie Bait Tank Problem

[makobob]

There is a black plastic fitting on the end of the pick up hose, make sure the opening is pointing towards the bow of your yak, pumps usually go all the way bad, so I would try the f/f battery, this should be done in the water. Good luck.

Perhaps the tubing isn't the correct length. Shorter for outback, and longer for PAs. If trimmed too short, I could see your scenario play out.

I hooked up my 12v battery to it and it works perfect! I have it recycling water in a bucket right now to see how long this battery will last.

The old 6v battery must have been very weak because now I can hear the water pumping and the pump going. With the old battery I could barely hear the pump but thought it was working.

Thanks!

Step

1. Install bait tank on kayak like you normally do
2. Take of intake
3. Post picture of intake tube
4. 999.99% chance that we'll be able to tell you exactly what's wrong

The 12 volt batter works that pump on overdrive, so of course you hear it, and I am sure you can see a difference in the volume of water your pumping. The problem is that you really do NOT want all that volume. It will beat up the bait in the tank. All you really need is a little circulation and aeration. The 6 volt batter running that pump is ideal.

The first thing I would do, is check the pump like you are doing, but with the volt battery fully charged. If everything is good, then it has to be one of 3 things, 1). hose to short, or too long, as mentioned, 2). or the intake is sucking air. Or 3). the intake is getting clogged (kelp perhaps).

I'll charge the 6v fully and try it again in the bucket. If it works i'll take it out on the waters to see if it work. I'm pretty sure the tube and everything else is fine. The tube sticks out about an inch under the kayak. I'll try to get pics next time.

Have you checked your battery with a voltmeter?

[spyakker]

I tried to check how much "juice" is left in it but not sure how to do it. Searched it, and I think I need to use a resistor or something. I believe just using the voltmeter alone will only give you the reading of how much "juice" it can hold.
correct me if I'm wrong.

your pump is fine , you have already tested it at maximum voltage . a new hobie battery will test out at 6.7 or 6.6 volts . a strong battery is gonna be 6.5 - 6.4 vlts. , and so on . a questionable battery or bad battery is obviously under 6 vlts . putting the battery under a load would be ideal . . maybe autozone will check it for you . .assemble the tank and attach it to kayak . turn kayak over , and check how far the tube is hanging down under the kayak . the tube needs to be protruding below the water line of kayak . as mentioned above ,the induction side of the tube needs to be facing the front of kayak . have you eliminated this from the equation ? the tube should have a zip tie to attach the tube , and a rubber o-ring to make a complete seal . if the guy sold you a working tank , i would think the induction tube is long enough , but maybe he cut the length to fit his kayak . and finally already mentioned also , you can test the tank by placing in a 5 gallon bucket full of water , you will need to prime tank manually by inhaling on outlet side of pump . this can be done with a hose extension attached to the outlet side of the pump . there are posts on this modification . a constant supply of water will need to be added to bucket , like a garden hose hooked up to outlet . if none of this makes sense , feel free to pm for pics .
