Re: Live Well Issue
There are reasons to have a livewell running while underway. Ever run 15 miles offshore with live bait in the well? I have more times than I can remember and the livewell worked each time.
If you have a scoop or clamshell fitting, it may be facing aft instead of fore. The well shouldn't fill while the pump is off because the pump not running will (normally) not let more than a trickle of water thru. Depending on the location of your live well pick up tube, you may simply getting air under the hull and this is not allowing water to come in thru the strainer/thru-hull. And because of the venturi effect of water running under the hull, it may be countering the effect of the pump trying to pull water up, as the water running past is pulling it back out.
If you want to have the well running while under way, use a fore facing clamshell or extended grate fitting.
