Livewell not draining

[gatordoc]

I have just bought an'85 SF that appears to have the same problem. Whenever I run the livewell water just flows onto the deck when the hatch is opened and seeps out as well when itis closed (latched down). My drain and overflow lines empty out through the same through-hull fitting in the transom (there is a valve that can switch the mode of drainage). My feeling is that I may have to open a larger through hull drain for the overflow in the transom that is separate from the drain line. Thother possibility is to enlarge the existing through hull.

I think it's an issue of not having enough overflow volume getting out at the proper rate. Perhaps this is what you are faced with as well.

Anyone have thoughts or ideas on what would work best?

Thanks.
