Re: 3/16 instead of 1/2 " Stuffing ?
If you have to pound or otherwise force, cram or jam the packing into your packing gland then the size of packing material you are using is too big.
You should be using the largest size of packing that easily fits into the space in the packing gland. The tension from the packing nuts will make the packing material fill up the rest of the space.
Using an over sized packing material is a bad idea all around. You can score your prop shaft if the fit is too tight and it would be unlikely that you could achieve the proper drip rate using oversized packing material. Been there, done that; had to replace the 1/4" packing for 3/16" with my 1" shaft to achieve the right drip rate.
