I also have 2 pumps on my 2000 3500 Open (not sure what Open you have). I used them like this: Pump 1 which is louder (for unknown reasons as they are the same pump same mount) I use during the daytime. Pump #2 I use at night for when we use the head, ice maker runs so it is quieter and doesn't wake us up. I use them seperately so I do have a backup just in case one does go out but I still like to use them both just to exercise them. When I need more flow I will turn them both on for example if I need to rinse down the cockpit of fish blood while fishing or something like that.
Not sure why one doesn't shut off but if you have a water pressure tank (accumulator tank) you might want to replace or at least check it because the baffles do break in them more often than I would have thought. Just replaced my second one in 3 years. There is also switches on the pumps that turn the pump on and off so maybe the switch on the pump that is continuously running if bad.
I used Jabsco pumps I go from West Marine to replace mine, 50PSI I think. Didn't want too much pressure as I don't want to blow a fitting on the boat someplace and 50PSI is more than enough for us.
