I have a '96 Champ 202 & some water is leaking into/ out of my livewells. When I close the remote drain valve & run to a spot and fish for awhile I'll notice I'll have water in my livewells. Also if I fill my livewells up after awhile I'll notice that some water has left the livewells. I've replaced the livewell valve, cartridge & livewell switch. Not sure what else I need to do so any help.would.be greatly appreciated.
