From what you are saying I think I'm going to forget the Echo and go with the Maruyama. Looks like a much better pump and they make their own engines. I do see where they mention agitation, must have missed it. Also, Solo uses a Honda 4 stroke, not a Kawasaki if anybody is interested. These things are all about the same price give or take around $50 so I might as well go with what I think is the better machine.
Thanks for the help.
