    Hi guys,
    The drive shafts stuffing boxes were repacked with 5/16” Teflon packing 2 years ago, when should I look at replacing the packing? I adjust/tighten the nut every-time I return from a cruise. But it’s getting harder to adjust, could I install a couple more packing rings while the boat is in the water, and do a complete job in the fall when out of the water?
    Cheers Rob

    Rob you can do that or just clean the old stuffing out and replace. Normally I get two wraps in, then wait a week or two and add a third. The packing nut will compress the first two enough to add a third.

    Might be that they got two in and never added the third.
