Absolutely. Galvanic is probably the hardest to trace. Most people (7 out of 8) are on the alkalai side of ph, whereas I am the other one. Acetic. I have to be careful. Some people carry an electrical charge on occasion. If a harp feels tingley in your mouth or tastes bitter, you are probably galvanic. Either too high or too low. I tend to burn the plating off of harp covers.

Yeah, zinc anodes only cost a couple dollars, whereas props, sea valves, intakes, exhausts, cost several hundred. :)
