Packing nut temp?


Recommended Posts

Replaced packing for first time in 10 years. Temp was 175 when hand tight as much as I could get. Seems hot?

Backed it of a few turns so it’s “just” hand tight. Now tops out at about 115.

What’s the right temp?

I got the virtually dripless goretex stuff. I can’t get it to drip at all. (It was literally peeing before I replaced.)

IMHO the "right temp" is just tight enough that it barely drips and isn't hot to the touch.  115 seems plenty cool.

Thanks for this. I feel better.

I loosened the nut as much as I dared while on the water, and it just doesn’t drip no matter what.

I’ll recheck things after I put a couple of hours on it.

FWIW this is what I bought: https://skidim.com/shaft-packing-virtually-dripless-3-16.html

Says “hardly ever drips” so I guess I did it right.

Definitely...these thing tend to "break in" after a period of time.

Put two hours on it, today. Temp down to 85 after some break-in. Still no drips. I’m calling it a success!

For anyone who stumbles upon this thread, here’s a tip: those $30 aluminum wrenches are completely unnecessary if you have the right tools. I regret buying one because my Knipex plier wrenches worked perfectly (and better - I did try the special wrench since I paid for it). Well, I guess the special one is good to keep on board for emergencies. I’m sure as heck not keeping my Knipex set on board!

I had the same thing happen when we did the packing on my in-laws lxi.  Got hot, no drips no matter how loose I made it.  We ran it hard, let it cool down, repeat a few times and then it finally started dripping

In my configuration, there is the v-drive right above the packing, and 2 ballast pumps on either side...it's pretty tight.  It's not impossible, but I think they're almost required for v-drives.  One day you'll save someone's bacon if they need one.

I just use a big channel locks and one of these Proferred Plumbing Adjustable... https://www.amazon.com/dp/B016OK8QNM?ref=ppx_pop_mob_ap_share

 

 

I know they’re not the cheapest, but once you use these you’ll never look at another adjustable. That said, your $30 adjustable is a lot more useful than the aluminum thing I bought (but I have a direct drive).
