502 stang,
After re-reading your post... you definately need to lower your outdrive via spacers. The fact that it takes a 6-blade to even marginally hook up, along with the lack of bow lift says you need to go lower.
I have done spacer testing recently, with my prop shaft centerline starting at 3.5 inches below the keel. In half inch increments, I lowered the outdrive using spacers. Every time I lowered it, I picked up speed.
Attached is the spreadsheet I made.
Hope this helps,
Chris

502,
The original prop delivered with the boat was a 28 Maximus. Boat went 77 mph with 16% slip.
After talking to Brett at BBlades this morning, I will try going up in 1/2 increments while testing the Herrings.
My boat is in the Portland boat show right now, and then will be in the Seattle boat show, so there is a delay in testing untill Febuary.
You can give me a call if you want, and I will further discuss my findings.
