Then why the heck do they give you the option then ???????? Any way that's the way I've been doing it for 3 years on one boat, 6 years on another boat, and now I'm into my 4th year on this boat - With No Problems. So I and many other people I know will continue to not use sea water to flush with and I'm not the Slightest Bit Worried about any problems you may have imagined.
