Anyone know the right size of stuffing? It's the bronze factory gland with a 1 inch shaft. Boat a long way away and want to get sorted before haulout in a couple of weeks...

Are you using flax or the graphite ultra x ?

I used 1/4" ultra x for my 1", but depends what stuffing box you have.

4yrs since I did it last. No grease required.

From US.
I have no long term experience with it, but good reports. I have enough for a repacking if your keen. I can order more.

I would advise using synthetic fibre PTFE (teflon) impregnated packing, flax will not last - it rots, carbon (graphite) on stainless is never a good thing.

I used to repair and prepare for survey boats for a living, seen all the salesmen push their product, stick to the white stuff. PTFE asbestos was the best, not sure if you can still buy it.

Yep, I'd heard that. Regarding graphite on stainless and wear problems. But no definitive results in field.

Maybe I'll swap mine out.

Just to confuse more:

I'll stick with what I've got. A couple of drips a minute. None when shaft stops.

Just warm to touch at 2800rpm.

Forgot I had already been down this rabbit hole.

Mines GFO not Ultra X.

Wow - yet another boat ownership rabbit hole! Lucky I'm a nerd at heart. 

;-)

 

Lateral - would love to buy a little of that packing from you if that's an option. Will PM you.
