Through-hull Transducer Maintenance
If your boat is kept in the water, performance of your JFC-7050 Sonar will be adversely affected by
accumulations of sea growth on the face of the transducer. To prevent sea growth effects, the face of
the transducer may be coated with antifouling paint specially formulated for transducers. Do not use
regular antifouling paint on the face of the transducer. The bronze housing may be coated with any
antifouling paint. If fairing blocks are used, especially if made of wood, complete sealing prior to
painting is important.
