1. A bilge pump, comprising:

  • a first field effect sensor, within a sealed housing within a bilge, the first field effect sensor configured to generate a first electromagnetic field and sense a presence of fluid proximate the first field effect sensor by detecting variations in the first electromagnetic field;

    a second field effect sensor, vertically aligned below the first field effect sensor with respect to the bilge, the second field effect sensor configured to generate a second electromagnetic field and sense a presence of the fluid proximate the second field effect sensor by detecting variations in the second electromagnetic field; and

    an actuator configured to operate an electric pump in response to the first field effect sensor detecting the presence of the fluid proximate to the first field effect sensor and stop operation of the electric pump in response to the second field effect sensor detecting the presence of the fluid proximate to the second field effect sensor.
