I was talking to some of the locals out there. Hes running a 18 foot Baja with a hot 350 in it with thru hull exhuast. I asked him the same question you thought. He told me as long as your not being a d*ck, they leave you alone. I would love for ya to come out by me. We got only about 2-3 jets out of the 1000's of boats on the lake. But your going to have to run some serios baffles in them headers or run thu hull. They are cracking down hard around here about that. As you can see, so is your area too..
