Bronze and cupronickel sit in seawater for many decades ...maybe a century or more if isolated properly or with similar metal...hard to imagine a regular fresh water flush does much more than help with the occasional marine buildup (not corrosion)...which should be done just to flush scale, etc out every decade or so.

I guess it may depend on where you're boating. But in the south, you better be flushing your coolers, especially the coils for your A/C units, way more often than once a decade.
