I figured unprotected (non-plated) aluminum structure and stainless screws combined with moisture (fresh or salt) caused most of this corrosion. I'm adding these Polyelastomer Cushioning and Sealing Washers .060" thick against the powder coated parts. Generally it will be:

Screwhead > SS Flat Washer > Poly Washer > Part > Poly Washer > Part > Poly Washer > SS Flat Washer > SS Locking Nut

Sounds about the same as what Porsche does. Maybe a mylar film could work as well?

I found one of those tables. This one is for salt water.

I just counted on the powder coating and a dab of Tef-Gel corrosion inhibitor. So far, so good, but I'm in 98% fresh water, unlike you. Good thinking.

Assembly Time! Trying to get it done and delivered tomorrow. Engines go in next week. :D

Lookin good Nort. I can not beleive you are working so close to your car!

Man! That looks familiar. I remember seeing that every time that I closed my eyes four years ago!!!
