Livewell Pump Question

[sglass]

Hey guys I just replaced one of my livewell pumps and I have a wierd problem. The pump will kick on and sound like it is working but will not **** in water to aerate the livewell. When I unscrew the pump from the housing and stick it back in real quick it starts circulating water like a champ. None of my hoses leak so I am not sure why it does this. Any suggestions???

Sounds to me like the impeller is dragging on something in the lower part that it screws into.

I will check it out. I bought the housing and the pump new so it shouldnt have a crack in it. If it does I will seal it up. I will also check to see if it is too deep in the housing and possibly not letting the motor spin. If that were the case though it would not work when I remove it and place it back in there right??

Your supply hose might need to be rerouted around the other hoses. On my friends boat, anytime you first start the livewell pump for the day we have to push the supple hose from pump to livewell down. It gets an air lock in it. Once we do that, it works fine all day.

Some water pumps are not self priming, meaning if there is no water inthe pump it will just spin the propeller inside and not draw a suction. Try and dip the pump in water and see if it will move fluid through all the lines. Also if there is a small imperfection in the propeller inside the pump it may just be DOA out of the box.

Thanks guys I will work on her tomorrow and see if I can fix it. If not I will just prime it every time I go out. I spent 80 bucks on that pump so I am not looking forward to getting another one.

Make sure the pump is running the right way and not backwards. There is a + and - wire.
Brown should be + and Black -. Just a thought..
