I use boat trailer wheel bearing grease anytime SS is threaded into Al around salt. Learned the trick from outboard mechanics. Pull a gearcase ten years after using the stuff, bolts come right out and are still greasy.

Anytime I buy an outboard, I take as many bolts out that are easy to get to and grease em up.

The grease is cheap and readily available. Probably does the same thing as the tef gel, keep the water out of the galvanic couple and all is good. I'll look into that tef gel.
