The seal isn’t pressed all the way in on the one motor.  That might have something to do with it.

Just a reminder but stock 5.5 and 7.5 props are of different pitch. You don’t want to switch them around as a 5.5 prop on a 7.5 will allow the motor to over rev while a 7.5 prop on a 5.5 will make the motor lug.

Yes, most likely this is the issue.  I ran into a similar problem when I failed to press the seal all the way in on a 58 gearcase.  You can just use a deep socket and tap it in the rest of the way.
