Corrosion: How to Protect Marine Electronics (A Practical Guide)

Why saltwater is brutal on electronics Saltwater contains chloride ions that accelerate oxidation and electrochemical reactions. Even a light salt mist can leave a conductive film on PCBs, displays, and connectors. Over time that film traps moisture, promotes corrosion under components, and creates leakage paths that cause intermittent faults. Common symptoms Random resets or dim/garbled displays Sticky or noisy button/encoder inputs Green/white “fuzz” at solder joints, conne
