    Need some Help
    I've picked up a 1982 Post 42' project boat. The live well is suppose to be set up with a pump which has a reverse cycle. There is a on-off-on toggle switch for live well and live well pump out but can't figure out plumbing configuration. Can anyone help out.
    Thanks Much....

    Is a livewell OEM on an 1980s 42 Post?

    I think my owners book has some stuff in it for the 42.
    I willl check it when i get down to the boat.

    BTW,
    I have a 46 and it took me almost a month to find the through hull for the generator....

    Couldn't you just have followed the raw water intake hose to the seacock?

    As for the livewell configuration, does it have a drain high in the tank that just gravity drains? Any pump that is reversible and rated to pump saltwater would be fine to use.

    This looks like OEM but I'm not positive.
    When I purchased her the pump was missing and the seacock had to be replaced.
    The live well does have a drain that is high in the tank for regular water discharge while the live well is activated. The fill hose is also up high and there is anothe hose which is attached at the bottom of the live well and that hose runs along side the fill hose to where the pump is suppose to be mounted. The way I'm looking at it(which is what the problem is) I have the inlet hose from seacock which attaches to one side of the pump, then I have anothe hose which attaches to other side of pump which then connects to the fill on the live well. Now this leaves me with another hose which is attached to the live well at the bottom and know where to attach it to the pump... to drain

    Thanks for the input

    I don't think this is a factory setup. The only thing I can think of is a Y fitting after the pump to both the fill and drain lines. You could put one way valves in each one but they would clog and never work right. So maybe the previous owner would put a cork\plug in the drain hole while the pump was on fill so the water would only travel to the top fill hose? Then to drain, pull the plug from the drain hole and plug the fill hole. Then the pump would not suck air from the fill hole and pump back through the seacock to empty.

    Just a guess.

    No, it's good to have water coming in at both the bottom of the tank and near the top. It helps to keep the bad stuff suspended where it goes out the overflow at the top of the tank. If you have a Y and enough flow and possibly smaller fittings in the tank than the hose, you should get good water flow out of both intake fittings on the tank.

    I'm headed out of town for a few week and will try this when I get back. I'll let you know the results.

    Thanks for the advice
