. . . or something like that. I'm replacing my rudder ports. I need to ensure that the packing nut and jam nut do
not seize to each other and to the port, becoming one big useless lump, as they had previously. Should I apply
dielectric grease to the threads and contact surfaces between the nuts? Anti-seize? Basic bearing grease?
Also, I plan to slack the locking nut and re-grease periodically going forward. How often? Monthly? Annually?
Thanks.

Dielectric grease is NOT what you want. I would not use anti-seize unless you know it's compatible, as most are metal-based. A VERY LIGHT coating of some basic axle grease would probably be fine. I would think "multiple years" as an answer to the 'how often' question. I would certainly not expect to do this monthly or annually, unless you are in a severe corrosive environment.

While you are at this, maybe consider making sure your bonding system is all connected and working as it should. Some of the issues you may have encountered could have been made worse by a compromised bonding system.

Use Tef-Gel...

Thanks. Good input from all.

Yes, I'm making certain that everything that should be bonded is bonded. Even though the boat has some years on it, it has relatively low hours and is pretty much unmolested from original.

Very interesting on the Tef-Gel. I'd never heard of this product, but the reviews are outstanding, so I'm going to give it a try.
