I bought a good length of graphite packing rope to use on my Berkeley. How long do I cut each rope?

I've probed the internet but the answer is not forth coming.

Thanks

While you have them out drill an tap for a zerk...Keeps them lubed.

I seriously doubt that pumping grease into a zerk at that location is going to do anything to lube packing where it is needed(between the packing and the shaft). I could be wrong though...

That's been my experience as well. I did drill a hole into the housing and installed a Zerk and tried greasing it. Doesn't get to the shaft unless there's a lantern ring. I actually did make a lantern ring, but I'm still not going to use grease, it's too thick to travel between the shaft and packing rings. My whole problem is that since I'm using the boat in a static mode to pump water for a jet pack project, there is no pressure built up from a moving boat, to force water into the packing for lube and cooling. Instead I'm going to push screened water from the engine cooling line, into the pump via a fitting I installed where the Zerk was and lantern ring between the packings. Should keep them lubed and keep air out, replaced with water.

This is the link to my thread here about this problem I've been having and think I have solved finally.

I put a light amount in mine every 3 trips or so and no water in hull...seems to be just fine in my pump.
