My drive shaft (on the boat) is leaking (steady stream). I am going to try and just tighten the packing nut to maybe slow it down a little but if I have to replace the packing what's best to go with? The flax rope packing or the GFO fiber packing? Thanks for the help as usual.

Here's some good choices http://www.skidim.com/products.asp?dept=1032 :D

Definitly start with the tightning

Seems like most are going with the dripless packing. IIRC, that's standard on MasterCrafts since about 2006.

When I first bought my boat it was leaking like that. I was able to just tighten it. Just go a little at a time, and watch. Don't over tighten it. Now, I just but 1/8-1/4 turn a season, and it's good. Remember you want it to drip a little.

This may be of some help in tightening,
Here is a simple procedure for replacing and or tightening the stuffing box,
Replacing and Adjusting the Shaft Packing.
Replace the shaft packing. Be sure to install two or three pieces.
Loosen the jam nut on the shaft-packing gland.
Back the gland nut off the packing gland assembly.
Dig out all the old packing material.
For a one inch shaft, cut two to three pieces of 1/4"dia. packing material strips so they are 4 1/8". Place one of the packing strips into the packing nut. The end should butt together. Place another piece in the packing nut, this time orienting the seam 180 degrees from the seam of the first piece.
Slide the packing nut up the shaft.
Slide the shaft through the Packing gland assembly and into the strut.
Screw the packing nut onto the packing gland assembly. Tighten it up as much as possible by hand. Then using a wrench, turn the nut a 1/2 a turn forward and a 1/4 turn back. Then turn the nut a 1/2 a turn forward and a 1/4 turn back. Then turn the nut a ½ a turn forward and a 1/4 turn back. This will pack the packing fairly tight.
Back the packing nut off the assembly again. Then thread it back on. Tighten it only as tight as you can get it using your hands. This should be almost the perfect tightness for the packing gland so that it does not leak, yet not too tight so that the packing burns up.
Tighten the Lock Nut up to the Packing Gland Nut.
If you want to add the third piece of packing, do so when you back the nut off after you packed the packing. Then tighten the nut only as tight as you can get it using your hands. This should be almost the perfect tightness for the packing gland so that it does not leak, yet not too tight so that the packing burns up.

BIGMAC... you say in the video the guy as the reverse problem? What do you mean and what is the fix?

I have owned my boat for 10 years now (520+ hours), and to date my packing has never leaked. It doesn't even drip. I have never adjusted it and it has never leaked. I guess I am just lucky?
