Bilge Pump

The bilge pump is located at the rear starboard side of the control room. It is operated by the use of a fist sized red lever right bellow the bilge and compressed air gauges. While submerged the boat will slowly take on water, the greater the depth the greater the rate. This has the same effect as adding ballast to the ballast tanks, the boat will get heavier, and start to descend if no measures are taken. Using the bilge pump will evacuate the unwanted water from the boat, but will also make the boat more detectible to vessels equipped with hydrophones. As such it should only be used when well outside of detection range, or when the enemy already has a fix on your location. It is also desirable to use the bilge pump at shallower depths, as the lower outside pressure allows it to evacuate the water faster.
