Default Re: Sacrificial Anode

I put a sacrificial anode from the Boatzincs place (like John in Illinois linked) into my flathead about 10 years ago. Last year I checked it and it didn't have any corrosion or erosion on it. It is screwed into the top sender port of a stock Ford of Canada aluminum head. But, I also use antifreeze that is made for modern motors with aluminum components.
