    Troubleshooting Automatic Bilge Pump

    I have a 99 Super Sport with the bilge pumps that are designed to do a test pump every 5 minutes or so and they will continue to pump if they sense water in the bilge. My rear one is working fine but I am suspecting that my belly one may not be working. I could just be paranoid but I haven't seen or heard it kick on all year. My bilges is pretty dry but being a V-drive any water usually accumulates in the stern so maybe the belly pump just never has anything to pump. Or maybe the stern pump takes care of anything in the belly when I am on plane. There is no way that I know of to force them to manually come on is there? My first thought is to check the wiring with a volt meter to make sure the pump is getting power but I am wondering if power is constantly going to the pump as long as the ignition breaker is on and their is a circuit in the pump that activates the pump every 5 minutes? Or does something else control the power going to the pump every 5 minutes? Maybe I will just stick my head in the ski locker and remove the access panel for 5 minutes and listen for it to kick on before I start troubleshooting an issue that may not exist.

    The pumps always have power, when switched on. Having said that, a V-drive boat will collect most of the bilge water in the back of the boat. With a Python engine, even more so.

    You can unclip the bilge pump body from the blue plastic pump base, screwed to the floor. feel the two tabs, 180 from each other on the pump body, and squeeze them, and the pump body lifts straight up.

    If you turn the power to the pumps off, wait a second or two, and turn the power back on, the pump should run for a few seconds.
