I've got no real comparison for you (being I'm a 2 smoker) but this what I get with mine with a 14x19ss prop. Yours is much better.

Idle 800rpm - 4mph - 3.38mpg
3900rpm - 30mph - 2.71mpg
4200rpm - 37mph - 2.63mpg
WOT 5100rpm - 44mph - 2.32mpg

I really need to put the other prop I've got on it to bring the rpm's up. Just too lazy.
