help

Try a rotation change. It is the first thing I would try as you can do it with your existing hardware. It will change your stern lift. # of blades will also change lift. There are many other things to try if this doesn't help. It may give you an idea what the boat needs.

I would try the rotation game and also possibly reduce some of the cupping as it's trying to lift the bow and dropping down.You may need to bump the pitch up a 1" if you do this .Darin
