I run an 09 Puma FTD with 09 Mercury 250 Pro XS and turn a 26 Fury to 6000 RPM with more left. I would like to try a 27 Fury, as I am absolutely confident my engine will push the 27 pitch prop close to 6000 on the top. I am, however, concerned that hole shot may suffer. I am going to ask Ivan what he thinks. I am pushing 78.6 mph at 6000 RPM. I could turn more RPM, but I do not want to exceed the maximum recommended RPM. I just know that I can get another 1.4 miles per hour from the boat to hit 80 mph, my goal. I have found through my years of fishing that if you snag a bass at 80 miles per hour, it takes the fight right out of them. Corky
