I was doing some research into winterizing my boat (34' Sea Ray) myself this year and I came across this product called Sea Flush. The website (seaflush.com) had some videos of the process and it looks like something I could easily do. I know enough about the overall process to feel confident enough to try. Anybody seen this device or have any thoughts about it? It definitely looks simple but useful. Thanks for any feedback, winterizing season is a-coming.
