The electrolysis corrosion pictured below. All electrolysis is eliminated with the SeaBis System.
The cause of electrolysis corrosion appears below each photograph.
However the same effect has many causes.
Where electrolysis exhibits a gray coating, then electrolysis is flowing in two directions, at different times.
The SeaBis System makes all wet fittings, the hull / engine etc. electrically open circuit.
In Home terms we pull the (electrical) plug
out of the socket.
Fit the SeaBis System - its the most economic way for you to protect your vessel.
Fuel gauge.
6 weeks in the water. Electrolysis tracks from the body of the fuel gauge in the engine room, through internal tanks to the hull then to the nearest conductor to the seabed - the anode. Note the anode has not depleted. Its good action has been swamped by the electrolysis.
