Trust me, rain water and lake water will do it too. Most crevice corrosion takes place well above the waterline on boats due to rain water leaking past SS fasteners and into the core of the deck or superstructure. There's very little stainless steel crevice corrosion with underwater parts because builders know not to use it wherever it would be a problem.
