    On my 2004 240DA the bilge pump seems to be on some sort of timer. It cycles every ten minutes or so on it's own regardless that the bilge is bone dry. I will cycle even when the batteries are shut off at the switch. While this seems like a very good redundancy while slipped, it is a battery killer in my case where the boat is on the trailer in storage through the week. Is there a way to change this feature?

    I’m betting you have a pump/switch that this is a ‘feature’ on. We usually change them to a manual pump and switch. Post a pic of the pump and switch.

    They make a water sensing pump that eliminates the float switch. It turns on and then off if it doesn't sense water. That sounds like what you have. Bilge pumps usually bypass the battery switch so they are always available to pump. I would replace the pump and switch to a more traditional setup. About $200 and only a one knuckle job.
