New member here. Recently purchased an X19 Pro with the Yamaha 175 VMAX SHO. Been going through the break in period and doing some fishing. I'm really liking this boat. Thanks to the guys here I have a better understanding of how I need to set the motor and most probably what prop to use. My RPM's are running low for this motor. 5000 to 5200 RPM is tops. Has the 23 pitch PowerTech prop. I'm going to measure ptp next week when I get off work and go from there. Current water pressure is running 23# to 24#. Top speed is 55 mph on gps with 3/4 tank fuel, me and gear. Open to advice from the experience here with this boat. Thanks!
