I'm doing a bit of work on the boat that required more fixtures, wondering what others do to prevent dissimilar metals causing electrolysis i.e stainless bolts, I'm sure a few on here will have had a bit of experience with this stuff.

I made plastic bushings for where S/S bolts went through the aluminium. For things like the transducer screws into the transducer bracket, I greased them, and removed and clean each year.
Be sure not to use any copper or brass fittings directly against the aluminium.
I'll be painting holes where can't get plastic washers in, hoping that's enough to prevent issues
We used a Teflon Gel (barrier) that was applied with a paint brush that basically eliminated any galvanic issues.
Might pay to see if something is available at a marine shop!?
SS and aluminium are reasonably compatible.
It's the alloying ingredients (alloy's) in the aluminium/SS that exacerbates issues.
The salts just as bad
@Fireflite. I think we used a similar product when I was marine in the US. It was a product called Tef-gel. It is absolutely awesome. Lots of S/S fittings into aluminium were coated in this This stuff
The range of what we think and do is limited by what we fail to notice. And because we fail to notice that we fail to notice, there is little we can do to change; until we notice how failing to notice shapes our thoughts and deeds
I just used a layer of silicon gell between the stainless washer and any alloy

Mercury is total death, you can watch it eat the aluminum before your eyes. Have never forgotton watching it as a science project. Drop of mercury on a sheet of aluminum within a minute white "feathers" of aluminim oxide poke out of the mercury and just keep growing and growing. Teacher wipes the mercury off and where he wiped grows a forest of white plumes.
