Hacks for re-installing Rudder Port

[billywro]

I pulled my rudder port on my 2008 220 due to a leak in the thru-hull-fitting. I was surprised to find a 2010 manufacture date on the port; meaning it was replaced (apparently poorly) at some point before I bought the boat in 2018. Was even more surprised to find absolutely zero evidence it ever had packing cord. Remarkably, the o-rings and grease seemed to be enough to stop water intrusion thru the shaft.
Anyway, I am looking for tips / hacks for the re-install. I will use 3M 5200 sealant and make sure all surfaces are clean, smooth and wax free. Particularly interested in thoughts on how not to squeeze too much 5200 out before it cures. Also curious how many layers of 3/16" packing cord to use. I've seen recommendations from 2 to 4.
Thanks in advance.

On the prop shaft nut, I always used 3 layers while making sure the gaps did not line up. Don’t worry about the 5002 setting up on you it doesn’t dry THAT fast. If they replaced the rudder I would check on the strut as well. The usual package we would bill the insurance would be for the prop, shaft, rudder, strut, and fiberglass repair.

Note: It's 3M 5200.

I want to share the jig I made to allow me to re-install the rudder port without an assistant. Just a small square of 3/4" ply wood with for holes drilled to hold Phillips head drivers (drilled undersized and tapped in with a hammer). Placed the screws thru, loaded it up with 3M 5200, lightly seated it in place with a jack, and then went inside to place and low-torque tightened the nuts. Let it sit for 48 hours and snugged it all up.
