A bilge pump includes an outer housing having an interior wall separating a first cavity and a second cavity, an on/off electrical switch located within the first cavity, and a single-piece float located within the second cavity and having a float body and an actuator arm extending outwardly therefrom, wherein the float operably connects the electrical switch through an aperture in the interior wall, and wherein the float is configured such that the aperture remains above a water line within the second cavity during operation of the pump. The bilge pump also includes a motor having a motor housing having a hub and a power shaft extending from the hub, wherein the motor is located within the first cavity of the outer housing such that the hub of the motor housing is located within a hub of the first cavity, and seal member having a centrally located aperture receiving the power shaft therethrough, wherein the seal member is closely received about the hub of the motor housing and within the hub portion of the first cavity, thereby providing a water-tight seal about the power shaft and between the outer housing and the motor housing.
