Is anybody out there?

Marine Warehouse is your best bet. They handle yacht-in-transit importation (only 2% duty IIRC) and low shipping costs.

oxidation, or chloride corrosion."

I suspect that Locktite in this case is just another anti-seize, anti-gall, anti-corrosion (take your pick) application. I use it, but I suspect Loctite's biggest benefit is that it makes me feel safer than an anti-seize goop because I imagine the anti-seize goop might come undone.

Loctite is a well proven anaerobic sealant. It has secondary benefits to minimise galling but its primary role is as a thread locker.

Brian Toss's advice to fill the voids with a sealant is intended to ensure there is no internal void where sea water can collect. It's an excellent suggestion andnwhat we follow.

You will still need to put something on the threads to avoid galling. Never assemble stainless threads dry. Anti seize or loctite will work just ensure you use a suitable antiseize.

I also didn't add any caulking or silicone. The instructions didn't say to add it and I understand SS off is best when exposed to air.

Unfortunately the stainless inside the stalok does not breath. Any moisture entering will then become stagnant. 3xx stainless will experience crevice corrosion when subject to stagnant moisture.

Brian Toss's advice is worth following.
