  1. I’ve had a Hydro 3011 since the early 90’s. Frankly this is one of the best machines ever made and produced at the peak of Japanese quality. The xmission is right up there with the same era Civic cars. It has literally been a lifesaving machine for decades and other than the gas tank has yet to drip a drop of fluid.
