    I have a 12v bilge pump that I am using to circulate the water through a filter on the bait tank I built. I would like to put a timer on the system to turn the pump on several times a day for about an hours or so each time but cannot find a timer for a 12v system.

    I have a 110v timer at the house...Is there a way to convert the 12v setup to a 110 system? Does anyone make a convertor or transformer to do this?

    An invertor is out since I do not have a lighter plug available to plug it into.

    I found a 110v bilge pump but it is $100 +

    An inverter *is* the device that converts 12V DC to 110V AC. It's not against the law to cut the lighter plug off and wire it directly to your battery. Or to install a cigarette lighter outlet in the boat.

    But that's not the solution you want.

    What you're looking for is a livewell timer. They're available quite commonly, just search Google for them. Priced around $30.

    I have looked at the livewell timers & all I have found is one that has a max run time of about 3 minutes with an off time of about 5 minutes.

    I am wanting to run it for like an hour several times a day...

    I may have to look into the convertors...I never thought about cutting the plug off & hooking straight to the battery. How would I know which wire was Pos & which was Neg?

    James you could turn a battery charger on/off with the timer and connect a bilge pump to the charger. Even simpler, you could get an aquarium Power Head from the pet supply store. It will really move the water and is 110V.

    this is an old thread but in case anyone else is wondering the simplest way to do it with what he has.
    A cheap ice cube relay with a 120 volt coil and normally open contacts.
    You would fire the coil with the timer which would make the contacts going from battery to pump.
