Adding A Raw water Wash Down

[Stillrunning]

Is it best to have the tru hull in the hull or transom. The only thing I could figure is that if it in the transom I could not use while running the boat. What size thru Hull did you use 3/4" and you get plenty of water preasure with that unit. I'd rather spen a few bucks more to get higher preasure if needed.
