talking with a fiberglass guy over the weekend about jet intake placement and how to set it and a new to me term came up. it was a small gradual extrusion in front of the intake. it stuck below the boat maybe less than half inch and appeared to be about the width of the intake wide and maybe 10 inches front to back. he called it a "spoon". i suppose because it looks like the underside of a spoon on the bottom of the boat. i didnt have time to ask what it was for as he was a busy guy. can anyone help me with the idea behind this please?
