I'm looking for an accurate torque specification on the four bolts that hold the drive shaft flange to the transmission flange. (The flange that you would like to see less than .003 or less between any two points)

According to the document in this post, http://www.mastercraft.com/teamtalk/showpost.php?p=639908&postcount=16,
Install the bolts (3/8-24 x 1 " S30400) through the couplers and install the 3/8-24 Nylock Stainless Nut.
Torque the bolts to 25-30 Ft Lbs.
Double check that the jam nuts on the engine and the cotter pins on the trunnions are tight.
Double check that the shaft coupler bolts are torqued to 25-30 Ft Lbs.

I will look again but I didn't think the ones I have are Nylocks but the torque spec should be similar I would think.....Good article on the process!!! Thanks!
