I have a 2013 Z9 Nitro with a Mercury 225 and Tempest 25 pitch prop. I am having issues obtaining optimum RPM, basically running 5100 to 5300 WOT. Top speed loaded is between 58 and 60 mph. Currently have the motor at 3.5 " below pad. I was thinking about going with a 24 pitch to get the RPM's up and have heard good things about the Fury prop. Any suggestions? Also, any other suggestions regarding mounting height, etc would be appreciated. Thanks.
