Greetings;

Several years ago we replaced the stuffing box on our Victory Tug with a
packless shaft seal. Since then I've heard of one boat sinking and
another close to it when the stainless rotor loosened, slid forward, and
allowed water to enter the boat. Just today I discovered FAR more salt
water in the bilge than should have been there, and found a lot of
splashes around the packless seal. Evidently it's leaking.

I'm tempted to remove the packless shaft seal and reinstall the stuffing
box, but to use as packing the new hot stuff from the makers of GoreTex.
It is supposed to be so heat resistant you can crank down on the packing
gland until NO water seeps through. You get a dripless seal without all
the fancy mechanical stuff of the packless shaft seal system.

Anybody have comments on this issue?

Thanks,

I think you can adjust your packless seal by loosening the set screws and
sliding the ring a little bit further aft. This puts more pressure on the
two mating surfaces.
I believe there are two hex head set screws in the ring by the way. The
lowest one locks the ring on the shaft while the upper one prevents the
lower one from loosening. Not much chance of the ring moving. I think the
only hazard with these units is fire in the engine compartment. This can
burn up the rubber bellows and then you have a lot of water coming in.
Stopping it would be a bit difficult but not impossible.
