30 degrees of rake, measured by who? Turbo, Precision Propellers, Yamaha, or me?

Measure one i may have been misinformed i took the info from a bass boat prop test site...I maybe able to find that link again. Here's a pic of the lift on a 20' boat 8' beam about 4000lb's...Its a bit funny to watch a I/O run the channel bouncing on its tail like a bass boat.

Just making a comment hope your not offended Mr Blade's

No not offended in the least bit. I don't see that anything you are saying is offensive.
On a side note, your photo shows nothing to determine lift. Bow, stern or otherwise.

Happy New Year.

Agreed to a certain point...that pic show's a boat with a 8' beam and a 2' print. Bow lift...stern lift... you call the play./ Wetted surface drag etc..etc...etc. Just another day @ OSO.

This pic shows bow lift and the running attitude. Yours shows nothing but water behind a boat.
BTW, this pic is 24' 4500lb 8' beam boat.

Yes a side view makes it quite apparent, the wake shot i posted struck me @ first. I had never seen the boat running with a 2' slot behind it..but the attiude of the bow was similar.However the trim angle was less aggressive notice the prop wash is straight line back about two feet in height...no more trim was needed or chine walk would set in.
