I have a 2008 Stratos 486 fs with a evinrude e-tec 150 HO. I got it with a ss 22" racker 2 prop. I'm getting 5500 rps and 50 mph /gps but my hole shot is bad. Is there a way i can get more speed and get better hole shot. I have read that this boat should do mid 50's. Also what is blueprinting the prop mean?

Please help
