I think you should try 22p or 23p on that boat. You will sacrifice 2.5mph at 400rpm at worst, but should gain hole shot and better rpm with the 23p. Should be able to get a easy 53-56 with a 23p at 5400-5600? There have been several dealer wrong prop issues as of late here where I'm at. I had buddy buy 2017 Ranger 198 with 115 pro xs . He said he could get 4200 at best out of the boat, I looked at prop and dealer had installed 24p tempest on his 115? They swapped him for 22" and boat was at 5000 and low 50's after. Every boat and motor set up is different of course but its all physics in the end? My other friend just got the new TRX195 Tracker 150 3.0 Four stroke. It runs a 24P tempest and can get 58-61.2 on gps lightly loaded and around 5500-5600.
