Stuffing box with grease?

Hey Guys,

wondering if anyone has seen this practise. I have a stuborn stuffing box nut in an impossible position, tried penetrating ooils etc. Cannot get to it to unscrew it. It just leaks a bit, so not too worried about it but have owned the boat for foour years now (Ontario 28) and would like to be sure it was OK.
Then a fellow sailor I saw with a grease gun shooting it from the ooutside hull into the shaft housing through the hull; into the exterior regions of the stuffing box. He asked me if I wanted to try it and i said sure. Last year the stuffing box did not drip a bit. I tested it with a thermal sensor and the temp diff between sitting and running at 75% was only 5 degrees or so (the drive shaft.)
Has anyone heard of this? Will it reduce the need to change out the stuffing? Also, where the shaft goes through the hull behind the engine, there is a rubber housing surrounding the whole works, frm the stuffing box nut to the hull, what is this for? It is held on with some clamps if I recall (last summer was the last time I was doing Yachting Yoga !
Thanks for any help .
Mike

I don't know about shooting grease in from the outside but I suppose you could get some grease to flow past the bearing. My stuffing box on the prop shaft actually has a screw on grease fitting. I just tighten the grease cap every few hours and it seems good to go. As far as the rubber boot that is an essential part of the stuffing box making the connection waterproof between shaft and the hull.

Doesn't seem like a good idea from an environmental standpoint, that hose is an important part of keeping water out, this may be helpful.

Re: Stuffing box with grease?

I have had a grease gun hooked to my stuffingbox since the 80's, no problem. Friends have had it even longer. No problem. The thread on the end of the grease hose is a
1/8th inch pipe thread. So you can hook several hoses together with 1/8th inch standard pipe couplings.
The environmental impact is probably less in a year than in starting up an outboard.
