Electro-Guard manufactures custom reliable cathodic protection systems for you boat yacht or small ship. Prevent marine corrosion, incorrectally referred to as marine electrolysis.

We design and manufacture cathodic protection systems for your boat, yacht or small ship. Our systems prevent corrosion - frequently referred to incorrectly as electrolysis - to the underwater metal structures on boats operating in all types of natural waters. Our line of products includes both impressed current cathodic protection systems and controlled/monitored sacrificial anode cathodic systems. The impressed current systems provide protection without the worry and expense of replacing sacrificial zinc anodes - they come with a permanent anode and are automatically controlled.



Electro-Guard products are available to protect boats of any type of hull construction (aluminum, steel, fiberglass and wood.) and protect thru hull fittings, outboards, propeller shafts, propellers and all common underwater metal structures. Our monitoring instruments provide visual indication of system performance and warning of stray electrical current problems that can result from electrical faults.


All vessels are subject to corrosion. We can prevent that corrosion from happening and can halt problems which have already begun.
