The electrolysis corrosion pictured below was caused by electrolysis. All electrolysis is eliminated with the SeaBis System.
The cause of each 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.
Engine design. The engine is designed all single wire. Built in obsolesce. Using SeaBis System "Easier Method" will limit the electrolysis corrosion to barely visible in one year. This is a very simple method of electrical isolation and relies on the remainder of the boat being totally clear of electrolysis. Normal on SeaBis. Amber is acceptable - engine cooling system water conducts to the seabed.
