Stainless is better but still not totally immune.
If you use stainless, put some TefGel between them and use only 316
stainless parts.
Here's one chart. The closer there are, the better they work with each

Stainless looks a lot worse on that chart than reality.
My boat is bolded together with stainless fasteners, it gets dunked in
warm salt water about 100 days a year for the last 40 years and I am
not really seeing that much trouble.

Could be that your boat isn't made of cheap aluminum designed for fresh
water use only.
