ABSTRACT:
A cylindrical housing with either substantially straight or with inwardly tapering sidewalls is formed with a bottom portion that either tapers or curves inwardly until it meets a flat bottom area. A bracing section is connected within the housing to support a motor with fan or propeller blades operated thereby below the open top of the housing and above the bottom portion thereof. A plurality of openings are formed around and through the side wall above the bottom portion but below the motor so that when the housing is disposed in a body of water, and the motor operated, water from within the housing is directed upwardly to the surface of the body of water and additional water is drawn into the housing through the openings of the housing sidewall.
