My brother inlaw and I were out fishing this last weekend and I've got to tell you folks how a 225HO compared to a Mercury 175. I don't know exact distances, but I know I did more running around one day than he did. He used 16 gallons of gas to my 10. Din't think of it until he was talking about how much gas he had used and asked me how much I had used. Heres a big thumbs up to ETech fuel usage.
