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.
