Exactly. Wire it like GA posted.If i buy a new Rule 41 bilge pump switch and the Rule 500 GPH Standard Bilge Pump Kit w/Float Switch 12V 25DA-35A and i put the switch on auto that will give the float switch control of the pump so i just need a non auto pump correct?
You might be right. The carpet looks like the same stuff I got from Menards for my pontoon, Usually don't see that type on boats.Compartment you're looking at in those photos is a ski locker. The drain is to allow water to run back to your bilge.
Not to be an alarmist, but your bilge under the engine doesn't look right. Are you sure someone didn't replace that floor in the past?
