billmac Posted July 29, 2019 Posted July 29, 2019 My old 88 Cajun Maverick (my first bass boat) has a livewell in the stern and a small baitwell in the bow. It looks like they each have an input pipe, and of course an overflow hole and a drain. The livewell pump switch is in the front, and it has two settings, on, and automatic. I've never used it. I'm mostly an C&R guy. But if I do, what should I do? I'm assuming it simply circulates fresh water into the well. It doesn't appear to have an aerator. What does "automatic" do, circulate occasionally, whereas on circulates continuously? Quote
Elkins45 Posted July 30, 2019 Posted July 30, 2019 When my livewell switch is set to auto it kicks on the pump for a few seconds every 4-5 minutes. I have no idea if the timer function is built into the pump or the switch wiring somehow. Quote

It's in the switch - I did electronics design and construction years ago and a timing circuit is fairly simple and small even using analog parts. With the new programmable, digital chips - one chip to rule them all. Quote
billmac Posted July 30, 2019 Author Posted July 30, 2019 If you are on the water for 4 or 5 hrs, it automatic the best way to go? I don't know how much of a drain a livewell pump can be. Quote
FordsnFishin Posted July 30, 2019 Posted July 30, 2019 Use automatic if it's 75+ degrees out. The drain on your battery is minimal. Quote

I don't know how much of a drain a livewell pump can be. If your battery can’t handle the very minimal drain of a livewell pump kicking on a few times an hour then it’s probably not trustworthy enough to reliably crank your starter at the end of the day.
