I have a 30hp Tohatsu on my 648 War Eagle. Boat is rated for a 40hp, and seems under posered with the 30hp and my big butt on the back. Was reading about these Hydrofoils. Do they do what they say? I have issue with getting on plane, especially if me and another, plus gear in boat. Also, have issue with sight when slowing down, the bow stays up. What say ye?
