2-6 inches below the bottom on most single engine boats. It depends on if its a stepped hull, how much hp and how big of boat.
A 29 non step with 500hp is going need to be a lot deeper than a 29 stepped hull with 800hp.
Deeper gives more leverage to carry the bow and reduce the wetted surface. Stepped hulls don't need to carry the bow as much.

i would try the shorties first and see what you get. if you don't like the results or want more then go with an extension boxes i put 3 up imco boxes on my panther and had to change the engrine mount location, so unless you have to pull an engine i would wait on them.
i would be very interested to see how yours runs with shorties. i set my panther up to be 1 1/4 below the bottom with shorties and 3 1/4 with standard length with the 3 up boxes
