4700 Sovran raw water strainer

[Fixinbones]

Does anyone know what type and size of raw water strainers are on 4700?  My boat is in Florida and I can’t access it now. I am interested in putting a fresh water flush system that replaces the top of the sea water strainer with a hose intake and ball valve  but I’m not sure of the type and size of strainers and if this technique will work to pay the pond space constraints and where the strainers are located.
