Anyone replace these before? It’s an 87 champ and I believe these don’t work and would like to get my livewell up and working again.
That isn't your switch. That opens and closes the valves to let water in and out. There should be a switch either on your control panel/dash to power up the actual pump to pump in water that you'll need to find and check.
Push to close your livewell drains and pull to open. The switch to control the water may be labeled Aerate (livewell fill) and Hydro (recirculate).
