Livewell fishbox built without water pump

[Adventure208MA]

My 2004 208 was built without water circulator pumps in the livwell fishboxes. It was purshased used. Has anyone come up with a way to cirulate water/air through them without drilling a hole in the hull. I am trying to keep live bait fish to live longer. Thank you.

Assuming you have the bottom drain in the box....you could make a standpipe that fits into the drain port, drill holes in pipe so water can stay at a height you would want, yet drain. Then have a small pump for circulation. Manually fill the box with water as needed. You still need to run 12v for the pump somehow, unless your just keeping minnows then you can use a battery powered bubbler.
