This fully submersible 3700 gallon-per-hour Rule bilge pump has a water cooled lubricated ball bearing motor. Choose from 12V and 24V variants to suit your boat's electrical system. Rule submersible pumps are installed by many boat manufacturers because they offer good performance at a great price.

Their pump motors feature stainless steel shafts, water-cooling and a vibration-free centrifugal impeller that won't burn out if it runs dry. Each requires a panel switch for manual operation or a float switch for automatic operation.
