Salt Water Wake Surfing Help

Im about to trade in my boat for something that fits these following guidelines and need suggestions:

GREAT wakesurf
Good wakeboard wake at slower speeds (under 20)
Can handle salt water (internal cooling system that doesn't pull in the saltwater, and stainless steel parts would be great)
Can handle choppy water
Under 80k

I've heard the tige, and mastercraft have salt water options.. However gets quite expensive..

My reason for needing it to be salt water is that I go out in a creek with braccish water ever now and then, and would also like a boat that I could take in the bay from kemah to Galveston and dock there for the day. So it will also need a DEEP v hull to be able to go through some crappy water.. Help is greatly appreciated.
