Hi there. So heres my situation. I have an Alpha drive, and last season I upgraded my protection by adding the square shaped anode that mounts underneath onto the trim ram manifold. This year, included in my anode kit was a diamond shaped rubber gasket. The kit I bought last year didnt have one. I was always under the impression that for anodes to provide any protection, there needs to be metal to metal contact. Should I discard this gasket, or should I be using it?? I dont have a mercathode. Thank you for reading!
