My survey said that in order to be complaint with ABYC I need to install a galvanic isolator. During my research I see two on Defender.
1.) Lewmar Galvanic Isolator. ( $183.00)
2.) Pro Mariner Pro Safe ( $300.00)

I'll be on Lake Superior.
How critical is a Galvanic isolator in fresh water?
Does anybody have a recommendation?

All feedback is welcome and appreciated.
Regards,
Nick.

My opinion.... if you are in a marina with a lot of stray voltage... you need one. The last marina I was at my engine paint curled up in one year until I purchased my galvanic isolator. If I had not done that that stray voltage would have destroyed my engine. I'm surprised that your surveyor says that it is "required".

I bought my here:

Why do you need one?

It stopped the rusting right after I installed it. Cost was $99 and installed it myself.
