I'm not sure how or why a mechanic would replace a stuffing box, usually they replace the packing.
Do you know what packing material he used? There is some nice drip less material available but it can't overcome a mechanical problem. Was the boat on the hard when he worked on it? If so they I'd bet the shaft is out of alignment. Boats change shape after the launch for the new few weeks. If it was on the hard he could have done a perfect alignment job and then they boat changed throwing it out again. I would perform the alignment check myself and then decide if you need the mechanic back again.

In the past year the stuffing box leaks a lot after running the engine for a while. Mechanic supposedly replaced the stuffing, helped for a while but it is starting again. Tightening the nut helps for a short while. Where do i start looking to solve the problem?
