About this product
The Rule-Mate 500 is the pump we install most often on bass boats, flats skiffs and small center consoles. Its solid-state water sensor is built into the pump body, so there is no external float switch to jam with debris. It senses water, pumps it out, and shuts itself off. The low-profile housing fits tight bilges, and the base snaps out for easy cleaning.
