Working through diagnosis on my engine to see if my engine is down on power or my prop is no longer true. This season I am down 300rpm and 4 mph from this time last year. I usually run a fury 26p and I swapped over my tempest 25p from my old prop. Brand new condition. I looked like an idiot out there trying to get it on plane. As soon as it wanted to hop up it would blow out. I was having to do circles to try and get it up on step. Not the results I was expecting.
