I have discovered that we are supposed to be using magnesium anodes in fresh water because the zinc anodes wont work ( will not react to fresh water and sacrifice ) So I have looked to find the magnesium pencil anodes that I need for my cat 3116 engines and have been unable to find the correct size and or the correct brass plug.. I have new zinc anodes and plugs that I just bought but if they won't sacrifice and protect, there is no need to put them in . Does anyone know where I can get the magnesium anodes I need ?
