Not ice related but someone here will be able to answer, I'm sure. I want to build a livewell for my kayak. I want to hook up a Rule bilge pump(260 gal) to a 6V 7AH battery. will this provide enough power to push the water from the lake to the livewell? the water will drain out the side.

I think most of the pumps are 12 volt ..can you provide an actual model ?

Rule 360GPH bilge pump

Looks to be 12 volts not 6 volts

No different than the pumps that come in all boats. Obviously 12V.
-
I know that they are 12 volts but can a 6v battery operate the pump at a lower power, say, instead of operating at 360 GPH, maybe operate at 180 GPH?
-
I really don't know...I imagine it would, but it also would pull the batt down fast, I'd think. A standard 750 GPH bilge pump has a 2.5 amp draw. Any reason why you can't use a 12V? Most are same length, just wider and a tad heavier.

I use this pump to drain water from boats, canoes and kayaks, as well as to circulate water in a big cooler that holds my minnows. It runs on DC, but comes with an AC adapter so you can plug it in if needed. A thirty cent screen designed for your garden hose covers the intake, and plastic tubing is cheap by the foot at my local Ace store. If you rig a power panel, you can run both your depth finder AND the bilge pump off the same battery.

Mmmmmmm.......

was thinking that if using half the power, 7 ah battery might last longer.
-
No it doesn't work that way. P(watts)=E(voltage) X I(current) So for the same power out if you cut voltage in half you double the current. Now I'm not up on DC motor theory if you cut the voltage it may or may not run ok just slower but it may overheat and you may just burn it out.
-
With a DC motor, you will get about half the speed (at least at no load) with half the voltage. From motor and pump theory, I am guessing you will get about 1/4 the flow rate with 6V instead of 12, and it will drop below that as the battery goes down.
-
Just looked and a bunch of commercial made kayak livewell options. See what specs they use and copy or just buy premade
-
ok. thank you all. Probably just go with the 12v. I got extra battery. Moving onto the next question I just dug this out of my stuff. it's new. Does the intake need to be below the water line or can it suck the water up if mounted above water line?

The intake must be below the water line or your pump will constantly be working to prime the pump and could burn up quick if ran dry a lot. For times when you are not using the live well or pump you could find a rubber stopper plug so the well remains dry.

Maybe a check valve could be incorporated into the set up .. the weight of the check valve would keep it in the water at cruising speeds an do its intended purpose as well.

Sounds like a regular bilge pump tossed into the water is the best solution.
