Keeping Soaked marine electronics and equipment
Anytime electronic equipment takes a bath, if it was not already “off, ” turn it “off” immediately to prevent internal shorts from harmful sensitive circuits. Salt is then the big problem. Salt is hygroscopic, to say it attracts water. Salt dissolved in water forms an electrolyte that promotes galvanic reactions between dissimilar metals, such as a bit of wire and it is soldered terminal. Benny Cenac
In the humid marine environment, any electronics or electrical equipment into which salt has insinuated itself is somewhat more or less doomed, at some point.

For occasion, after a particularly moist and wild beat off the South Coast of England, your autopilot might go haywire, making all types of random responses. A day later it might seem to be to be working fine, but then develops a random tendency to travel peanuts. You should pause for thought before you rip into electronic units, taking them apart. Eventually one tiny grain of sodium, no bigger than a tiny pinhead, might have recently been left behind by an evaporating drop of drinking water. Every time the humidness rose, this speck of salt absorbed moisture and shorted out a hypersensitive circuit board. You can rinse it out with a cotton swab dropped in freshwater, and the autopilot can be in business ever since.
Water electronics that has experienced saltwater intrusion will need to be opened and flushed thoroughly with clean fresh water (first remove any internal battery). If perhaps the equipment can’t be worked on immediately, it is advisable to store it in freshwater than to let the salt go to work. As long as lightweight dried completely before being reconnected to a power source, the fresh water may do no harm-certainly less harm than the salt! Mineral state of mind and stove alcohol can even be used for flushing-alcohol, in particular, is itself hygroscopic, and so will usually tend to draw water away of components. WD-40 or some other penetrant/dispersant will have much the same effect.
When flushing, pay particular attention to airport blocks: Eliminate the wires, wash the cable ends, and use a syringe to flush the block. Take away fuses from their owners and wash both the fuse and holder. A coaxial cable connector, unless of course fully waterproofed, will carry salt and moisture, which will likely short the terminal. It will need to be opened, extensively flushed, and dried; if there is sufficient cable television, it should be minimize off and replaced.
Following flushing, the true difficulty is in drying out a number of the labyrinthine passages in electronic equipment, and in drawing water from surrounded components, such as capacitors. A great airflow will drive water from many unavailable areas. An air automotive compressor is best; failing that, use a fan or a vacuum cleaner’s tire out. An extended period of low heat-bright sunshine, or perhaps an oven, no above 150? F (66? C)-may be needed to draw out all the water from individual components. The part must be dry before reentering service. Any moisture is likely to create internal pants and cause rapid and irreparable damage. Before positioning the unit on range, test for normal immunities if known; then test between your power leads and equipment case for any signs of shorts.
Also if a rescue look at is successful, the equipment should thereafter be cared for as suspect: At the first opportunity return it to the manufacturer or an authorized local supplier for thorough testing and servicing by an designated South Coast Brighton Water Electronics Services dealer.
