Fuel efficiency vs Fuel Economy...
I am getting ready to repower my 18.5 Lowe and have spend many an hour investigating the various outboard marine products and the data that is supplied by each of their respective motors. We are currently running a 90 hp Evinrude and plan on going with the new etech 90. Here is one website that I found that compares 4 similiar 75 hp engines and their respective data. Points of emphasis: although these tests are not purely scientific, they do compare what similiar hp motors can do in regards to fuel.

Sacred Heart of Mary, pray for us now, and at the hour of our death. AMEN
For those who believe, no explanation is necessary....for those who don't, no explanation is possible
For the sake of his sorrowful Passion, have mercy on us and the whole world
