Abstract
A housing and sealing gasket encapsulating an unsealed DC motor for submerged use in water. The motor is held within the housing by means of a sealing composition and a biasing end cap to prevent motor vibrations. The sealing gasket disposed within a bearing cup receives the work shaft of the motor protruding from the housing. A flexible collar of the gasket engages the work shaft and is encircled by a biasing spring to insure effective sealing.
