Hey guys, my shaft started to leak something fierce, filling up and engaging the auto bilge every 8 minutes... we tried tightening the packing nut and lock nut, and we got it to stop dripping.

Running to boat over to the dock (5 minutes most) and it was dripping worse then before and didn't slow down even after stopping the boat.

I am looking at replacing the packing in the nut, but I am not to tech savvy and I have no real access to these boards up at the lake.

Should i get this handled professionally, or is it really ridiculously simple and a waste of my money to get a marina to do it?

Does anyone have photos of the procedure and a view from the rear of the nut?

I know this has been covered before, but I really need it laid out in some detail if I am going to attempt it up at the lake.
