I'm just curious if anyone has installed these on their boat or has
experience with them. The company is Marine Science Technology, and they
make a product that allows you to flush your engines (the raw water side, if
closed-circuit cooled) with the boat either in or out of the water. I'm not
going to go into all the details, but here's the web site if anyone is
interested (http://www.mstguardian.com) . I'm considering having them
installed on my boat, but would like to know what others think, particularly
anyone who has used the product for some time.

Thanks,
Steve H.
