Keel Bolts

Electrolytic action between the cast iron keel and stainless steel bolts, silicon grease or lots of siaflex maybe? 
A2 is poor quality stainless, A4 is best stainless for corrosion resistance in marine use but is not great in tensile strength.
You dont use stainless for keel bolts. High tensile steel
