I am running Yamaha stock 25 pitch prop on my 2007 and im going to try a 24 pitch Fury next week. Hole shot and top end is fair by myself with empty livewells and very little fuel. Add another person, gear, full livewells and a little more fuel then there is a big difference. I am also running 4 batteries with one of them a heavy weight Sears group 31 AGM. I think turning a few more rpms will make the difference when carrying a heavy load.
