Mario - sorry I missed your posts and questions about drive position. I remember seeing the drive install pics a few months ago when I made an earlier post and was going to mention it but looks like I got side tracked with links etc.
Indeed your drives are way too high and I imagine you will see nothing but drive and handling issues where they are.
I typically aim to install stern drives with the drive shaft/point of drive being around 3mm above the wetted running surface of the hull. Meaning that if you put a ruler along the bottom of the hull (not the tip of the vee) it should end up slightly lower than the center line of the drive shaft (assuming the shaft is horizontal with the bottom of the hull). Basically keeping the prop setup like it is a surface drive. I have seen drives installed deeper in the water though cannot report any experience as to how it affects the handling.
