First let me say Thank you to everyone that has helped with my previous posts. I am getting ready to replace the head gaskets on this motor and cant find the water deflectors in the heads. I have looked at a parts diagraham and didn't see them on there either. Does this motor have them? Also what is the best way to get salt deposits off of the water jackets? It appears this motor saw quite a bit of use in the ocean. Thank you again for all the help in the past.
