Did 175 miles of running this weekend. The boat had 4-5 people and gear so she was heavier than normal. fuel economy was pretty rough in the slop at this kind of load. 2.5-2.8MPG. In the smoother water, she got between 3.2-3.5 mpg, and when it was only 2 people maximum economy was 3.7mpg so i can safely conclude i haven't made the boat worse on fuel by much. Going to try the 17 pitch again and see how it performs with 2 people and full gear. I might end up needing to trade someone my 19 eco for an 18 eco if anyone out there wants to do so..
I can't attach the photos I took on my DSLR camera the image files are too big.
