330 Excalibur wont rev past 650RPM

SN206AUS, I'll try the old harness tomorrow. How did you know your potentiometer was setup incorrectly? How do you take it apart and flip it around? Thank you!

I think when I got my new one from Nautique Parts the sensor on the assembly or the spring was the wrong way around. Sorry cannot remember exact details I think I had to rotate the sensor 180degs.

UPDATE:
Finally got a chance to work on my boat this morning. I took out the new potentiometer and installed the old one (which was a replacement I installed in 2015). First start up, same issue, won't go over 600RPMs. Shut it down, restarted and it worked normally. 10 more starts and it worked normally each time. I am doing this in my driveway so I am cautiously optimistic, but it appears to be fixed. Thank you to everyone for your help!
