How do you tune your boats?

[GP73]

I hope Darin doesn't mind my reposting part of his message here, but I think this a great piece of information to keep in mind (about tunnel hulls?).

Also, generally speaking, when you raise and outboard up, you raise the nose of the boat. When you lower them, you lower the nose of the boat. The back of the boat is going to try to ride on a specific area of the prop (generally thought to be the centerline of the hub, but it's actually a little further out on the blade). So, where the prop is affects where the transom will ride, which, in turn will affect the angle of attack and ultimately, the height of the nose.
