Can someone explain this?
I was reading a website from a manufacturer of all welded aluminum boats.
There is a warning on the site that says: "DO NOT GROUND YOUR ELECTRICAL WIRING DIRECTLY TO YOUR BOAT. Direct electrical contact on the boat will break down the weakest point of the aluminum and cause holes in the boat. This is especially important if you are a SAL****ER Boater. This is called ELECTROLYSIS and is not a defect in workmanship or material." How could you avoid this? The motor is bolted directly to the metal transom and is grounded, there is contact there. I checked my aluminum boat with a VOM and there is definately continuity between the boat and the motor. Whats the difference in letting the motor ground to the boat and not the wiring? What am I missing here? |
