I pulled the 454 out and dropped a worked and chilled 525SC putting out about 650 hp and it was hitting about 80. Started getting a little sketchy.

I agree with the boat being able to run 60’s. We had an 25 OL 496ho, would go 61-62 all day 63-64 lightened up (Non-GPS). That was with a dah cupped mirage plus 23p.
Those boats like a little chop to get some air under the hull.
5# Procharger kit picked up 10mph 75mph was the best we saw with a 28p 4 blade mirage on that setup.

Was on water to get MPH and RPM to try different prop, and go figure mph gauge went out. Was still showing up to about 35 and wouldn’t go any more past that. So, I used a gps speedometer on phone and took video of that. Got about to 60 mph about 4600rpm. Any ideas where to check for mph gauge?

Update to some of the issues:
Boat started to die upon initial startup and couldn't hold RPMs steady. Swapped IAC and Temp Sensor w/ little to no change. PITA to get started and maintain idle, once it gear it does fine at idle, but now it really struggles to get on plane if at all. Boat now hits about 2500 rpm trying to get up w/ backfires every 5-10 seconds. Swapped cap, rotor, plugs, wires and new gas no change. Pulled out of water yesterday to dig deeper into the issue.
I did notice the drive trim limit insert 'celery stick' was on opposite sides, guess that could explain the initial struggle to get out of water from the beginning.
