This is a report from my build post:

I picked up some aluminum angle, plate , and square tube to start putting the mini jack plate together, which I want to do before I firm up the poling platform design to make sure I can tilt the motor up without hitting it.

Can anyone tell me in some detail how to set up the hardware to reduce the dissimilar oxidation. I tried Googling "Dissimilar Oxidation for Dummies, among other things, but nothing I found online really spells it out and I can't find the other MS posts that address it.

Stainless bolts, yes?
Brass Nuts or/and washers?
Plastic Washers?

The phrase y'er lookin' for is "galvanic corrosion".

What you probably are looking for is a zinc anode ( sacrificial zinc).

Avoid copper, brass or bronze when dealing with aluminum and salt water.

Anode can be had cheap from a marine surplus shop.

Thanks Brett and DuckNut. I was thinking the Zinc Anodes were for submerged parts.
