I have exact same boat. 6" manual jackplate though. 3 1/2" prop 2 pad get 68.5 gps w/2 talons I and 2 big guys. That's with stock prop after fighting chine walk.
Easiest would be to try a different prop, or if you have a local prop shop have them check it and verify the pitch. It acts like you have too much pitch but a 175 should be able to spin that 24P with no issues. Definitely not the speed you should be seeing for the RPM's you are running.
That’s what I was thinking. But I had a hotfoot put in by the place i bought my boat so I could just get it done while they had it and I think it has to do with the set up of that. I’m not a boat expert on nitros or anything but from what I see people run in their 150 and 175 Pro XS, I should be running mid 60s or low 60s at least l. There are 150s running faster top speed than me. I went from a 60hp motor on a tracker to 175 on a nitro and I only gained 22mph, and that just blows my mind that it’s not more
