If you're interested in experimenting, you might try moving it back a couple of feet if there's room in back of it. Back further, it would be working towards lifting from the center of the boat,possibly lifting the entire boat at speed rather than just the front as it does now.
Center toon could be a good idea. Might work out well for you, it's just that what you're looking at/suffering from, is a really poor install. A good idea gone bad if you will?
