Hello sailors!
Does anyone know what size and type of packing is best suited to the packing gland on the one inch prop shaft? The gland is the original one with the manual greaser on it.
Thanks,kris

I am not sure of the size but have seen that you can now buy packing with Graphite in it, I presume that this is to reduce friction on the shaft, less friction results in less heat so it "should" be possible to make it a bit tighter (maybe).

I think the stuff I used was impregnated with PTFE but that was about 8 years ago.   Your post reminds me that I should inspect and/or replace the packing next time my boat is out.

Thanks George, 
I am in the middle of a major haul out, so it is all ( well almost!) getting done. It is difficult to ascertain the size of the packing that was in the gland as there isn't much left...
It would be nice to access the technical papers especially the one re smelly bilges, but I am still unable to since the website was changed. Are you able, as a moderator, to find out why?
Thanks George,kris

Just done mine: it was 5mm or 3/16th.
But I do not think there is anything like a standard: depends on the fitting used.
I actually got the size too big (1/4 inch) and had a devil of a job trying to get it in, then could not quite get in only 3  of teh 4 layers.
The smaller size went in easily.
If you can, measure the difference in diameter: it should be snug but not tight until you compress it..  And you can also check the depth of sleeve into which you are going to have to fit it, then add screw thread overlap.
Hope htat helps.
