Electrolysis

[HURRICANEBOB]

I see white specks on the boat. The common ground your talking about, do i put the electrical tester on it and if so what goes to what like put red to neg on the battery and the black to the hull. I am not much for electrical testing or work. I called the dealer from which it came and they said sounds like a bad anode. Alot of the wires are buried and tied up to every thing its a pro team 185 tracker 2002. Thanks for the help

Set an electrical tester to "continuity". Put one probe on the NEGATIVE pole of the battery, then go to the hull metal with the other. Red or black probe on either. You should get no reading, meaning there is no flow from the negative side of the battery to the hull. DO NOT GO FROM THE POSTIVE POLE OF THE BATTERY, DO NOT, SPARKS......

Could be the anode, it should be on the lower unit of the engine. This is a relatively cheap attempted fix. Maybe 2 anodes, the trim tab is an anode, and part of the way up the lower unit there may be a second retangular one that sits in a pocket. Might ask the dealer did he mean one of the 2 or both.
