First of all, thanks for being so patient on answering some of mu dumb questions, your advice has been very helpful. I bought a boat used in salt water for 4 seasons to fresh water and want to keep it a long time. I was reading about the product salt away and was wondering if I flushed my engine with it in the spring time it might be a good way to help clean up any salt or corrosion in my fresh water cooling system. Any input?? Can I hook it up to one of those rubber cupped flushing thing you use with a hose? Or, do I need to hook it up directly to the engine and how do you do that? Would I need a new hose when I eventually took the saltaway "feeder" off? thanks again. tom
