Abstract: A marine anti-fouling system and method for inhibiting the growth of marine life on a submerged surface includes a control box and a number of transducers. The control box further includes a ultrasonic driver board, a magna-polar filter, and a power source. The ultrasonic driver board generates an electrical signal having an ultrasonic frequency which continually varies between 25 KHz to 60 KHz. A portion of this continually varying electrical signal is passed through the magna-polar filter where the signal is enhanced. This enhanced signal is then returned to the ultrasonic driver board where it is combined with the electrical signal varying between 25 KHz and 60 KHz. This combined signal is then electrically communicated to a number of transducers which are mounted on the submerged surface to be protected.
