The primary purpose of a bilge pump is to remove bilge water. This is essential for maintaining the safety and seaworthiness of a vessel, as excess water in the bilge can lead to stability issues, potential capsizing, or water damage to the boat's interior. Bilge water can accumulate from various sources, including leaks, rainwater, or operational activities. The bilge pump efficiently removes this water, helping to keep the vessel buoyant and operational.

Other options, while relevant to boating, do not pertain to the function of bilge pumps. Increasing speed generally involves propulsion systems rather than water removal. Storing fuel and navigating refer to different systems and components entirely, which highlights the bilge pump's unique and vital role in maritime safety.
