Yanmar 3qm30H Zinc locations

I'm currently performing winter maintenance on my 3qm30H engine which has been in fresh water for the past 2 years which I have owned it.
I changed my shaft and prop zincs 2 years ago & they currently still look like new(no corrosion) however I need to check my engine zincs as we are preparing to cruise after retirement this summer. My problem is that I cannot locate the engine zincs???
Can anyone give me some guidance as to how many zincs & where they are located on my 1979 Yanmar 3qm30H engine ??
Your assistance is much appreciated!
Thanks
One Chance
