Abstract: A boatlift buoyancy system for assisting in maneuvering a boatlift while in the water by adding buoyancy to the boatlift. The boatlift buoyancy system includes a first tube and a second tube attachable to the horizontal support beams of a boatlift that are capable of receiving of volume of air and/or water. A first hose and a second hose are fluidly connected to the first tube and second tube respectively for delivering pressurized air when buoyancy is desired for the boatlift. The first tube and the second tube also have a first aperture and a second aperture respectively within lower portions thereof for allowing for the draining of water when pressurized air is input into the tubes.
