I have recently replaced both the stator and trigger units on this 1982 Mercury 50hp classic. As I am definitely an amateur in outboard repair, I didn't properly mark the flywheel location. Presently the engine starts and idles very well, but the power at top end is lacking. I'm assuming I didn't get the flywheel back in the proper location. What procedure must I follow to accomplish this? Prior to the ignition problem the engine ran very well. Serial number is 5949922.
