Help finding correct zinc

[SeaEsta-12]

I recently bought new zincs thinking that I had purchased the all the correct ones, but my transom zinc was incorrect. It doesnt fit, and now I am lost as to what is the correct one for my transom.
I purchase part # 3854130.
Outdrive is a VP DP-SM. Here is a couple pics of where the zinc goes.
I also have a zinc on the actual transom that need replacing.
Anyone know what part number i need for my transom bracket?
Sorry for the pics uploading upside down. not sure how to rotate them in this forum.

The transom zincs don't have anything to do with the outdrive model persay
How about slotted zincs like this one Slotted ZHC-5 Zinc Anode or the
(ZHC-5S) or DP-612 Zinc Anode (DP-1)
They come in diff. measurements


Fresh water
DP-612M Magnesium Anode or
Mini Divers Dream Magnesium Anode
