Abstract
A submersible pump apparatus comprising a housing containing all the components of the pump assembly for using the submersible pump apparatus in a body of water. A float or a plurality of floats are attached to the top side of the housing for providing a positive buoyancy to the submersible pump apparatus. The float is provided with a channel for slidably receiving a single weight or a plurality of weights. The weight is used to overcome the positive buoyancy of the float and achieve a negative buoyancy for submerging the submersible pump apparatus to the bottom of the body of water. A sled is attached to the bottom side of the housing and comprises the combination of both legs and feet for supporting the submersible pump apparatus at the bottom of a body of water. A finder float floating at the water surface level is attached using a rope to both the weight and the housing. By removing the weight or weights from the float, a positive buoyancy is restored to raise the submersible pump apparatus.
