Yanmar (2GM12) sacrificial anode

I read some of the posts about the sacrificial anode removal being difficult. I have the same problem and now I'm wondering whether I even should try to remove it after reading that some engines used in freshwater don't even have them. I also tried to remove the entire plate that the anode is mounted in and it seems to be stuck as well.
Has anyone, after successfully removing it, found that there was a need when the engine is used in freshwater?

Re: Yanmar (2GM12) sacrificial anode

Welcome to the forum.
You should be ok if the engine has spent its whole life in fresh water.
If you read posts 15-17 in this thread it may put your mind at ease.
You would need a magnesium anode in fresh water if you wanted to fit one.
Cast iron last a long time in fresh water without anodes.
Try penetrating oil ( leave overnite)and a few hammer whacks on the bolt heads if you want to get the bolts undone but if you risk breaking them I wouldnt worry about it.
