The invention comprises a propulsion system attachment for use with a flotation board adapted with a mounting plug. The propulsion system comprises a shell housing which is adapted to be removably attached to a mounting plug member provided on the flotation board, a propeller motor, a power supply for the motor, and a remote control for operating the speed of the motor. The propulsion system also comes equipped with an air bag for maintaining buoyancy to the flotation board and to support the weight of the snorkeler. The air bag is provided with an air line so that the snorkeler can inflate and deflate as necessary to effect the proper buoyancy level. The snorkel board has handles for the user to grasp to aid in maneuvering the board. A supplemental air bag may be disposed underneath the rear of the snorkel board to help provide additional buoyancy to the board in the water.
