Have a conventional v bottom hull with notch.
The notch is 8" deep and the height is 8 1/4".
The hull was rigged with outboards and i bought the naked hull.
​​​​​I want to mount a #6 Drive now but don't have any ideas how much the propshaft should be above or below bottom line.
Any ideas?
Chris

It is a 27ft hull.
The engine produces about 1100-1200 HP.
The bare hull weights about 3400 lbs.
More race than pleasure (no stereo, no backseats, no cabin interieur ...) with eyes on top speed.

Being a single in a non-stepped hull, you are probably going to end up with the propshaft one to two inches below the hull (not the notch).
I would guess the prop will end up being a 17" (or slightly smaller diameter) four blade.
All of the above will help with bow lift.
