The contamination coming primarily from a body of water in which the boat operate. The contamination, if left on the boat hull while positioned on the boat lift and out of the body of water, will have an adverse effect upon the condition of the boat hull. A series of intermittent burst of fresh water from each fresh water discharge occur through a respective angle of discharge in a respective repetitive cycle of passes during the raising operation of the boat lift.
